(1) Your Virtual secret Network Connection

Having trouble connecting to the Internet at home try these steps before calling for help.

1. Do you have an Ip address? Try ipconfig /all. If you do not have an Ip address reboot your Pc. If that doesnt work power cycle your Cable/Dsl modem and routers and reboot your Pc again after the network devices are up and stable. Be sure all of your network cables are plugged in tight.

2. After your Pc reboots check that your network adapter is active and packets are flowing. Perform the ipconfig /all check again.

3. Check your connectivity by pinging some Internet sites. If that does not work, ping the loopback address 127.0.0.1. If that fails, your adapter may not be working or it is not properly configured.

To check your Ip address. From command prompt enter ipconfig /all (as shown in the picture) you should see an Ip Address and some Dns Server addresses. The domain name theory (Dns) is the way that Internet domain names are settled and translated into Ip addresses and is required for browsing the Internet.

Ping 127.0.0.1 - loopback Test (as shown in the picture). The loopback test is used to check if the Ip stack is responding. If it times out or you get an error the question may occur if any one or more of the following conditions is true:

*The Tcp drivers are corrupted

*The network adapter is not working

*Another aid is interfering with Ip

Check your network adapter, click the Start menu, Settings, control Panel, and elect Network Connections. Duplicate click on the Local Area relationship or the Wireless Adapter whichever one you are using. Be sure its Connected. If you have multiple network cards disable the one you are not using.

There should be Packets displayed in both the Sent and Received counters. If the Received counter is 0 check that the adapter has an Ip address. elect Properties.

Click the check boxes for Show icon and fill in me below. A twin Pc icon will appear on the lower right portion of the taskbar in the tray area and will flash while sending and receiving packets. You can place your mouse over the icon to get the status and click on it to get more details.

Tracert displays the relationship path to the target location and the amount of hops. Each hop is the trip from one router to another. Tracert is a handy tool both for insight where problems are in the network and for determining latency between hops.

Ping is used to conclude either a host exists and is active on the network and can conclude the round trip time to the device. You can enter a host name or an Ip address if you know it. If the request times out then the host is not reachable because it's offline or there is a question with the connection. Try some sites, if none work then ping the loopback address 127.0.0.1 Also, if your Dns is not working or properly configured you can only ping the host with an Ip address and you will not be able to browse the Internet.

If you are having intermittent problems, Perform a ping -t for 5 to 6 minutes then hit Ctrl C to see the results of the test to conclude if you are dropping network packets (lost packets). If you are, this regularly indicates an Isp question or Cable/Dsl modem problem. See Vpn Isp Troubleshooting Guide

(2) Vpn Troubleshooting Error Messages

Q1 Error Message: Remote Host not responding: or Unable to conclude the Ip address of the Remote Server

Cause: This indicates that the Contivity Vpn Switch never responded to the relationship attempt. The question could either be with the Contivity switch itself, (switch may be down) or your machine may be having a question resolving the Ip address.

Action: Try pinging your destination name (Example: Vpn.something.com). If you received a message that says "Request Timed Out" from the ping command, call your Isp to make sure that their Dns is functioning correctly.

Q2 Error Message: Maximum amount of sessions reached

Cause: This indicates that the maximum amount of users for the catalogue you are using are currently logged on.

Action: If you are the only user with Vpn to your account, it is possible to get this error if you restarted a relationship immediately after losing the dial-up relationship to your Isp. This is because the Contivity Vpn Switch takes up to one hour to conclude that your relationship has been dropped and log you off from your account.

Q3 Error Message: Login failed, Please consult the switch log for added information

Cause: The User Name or the Password is incorrect for the user name entered.

Action: Verify that the User Name you entered is correct and retype the Password before trying the relationship again.

Q4 Error Message: The corporal relationship has been lost

Cause: Your relationship to your Isp was disconnected.

Action: Re-establish your relationship to your Isp before you re-establish the Contivity relationship to the remote network.

Q5 Error Message: The derive Contivity relationship has been lost

This message can corollary due to a amount of distinct reasons, and there are some recommended actions you can take to try and re-connect.

Cause(s):

If you receive this error before the client connects then something is blocking a primary port (such as Esp port 50). This can corollary if your firewall is not configured properly and is restricting the primary port(s).

If you receive this error during a relationship and you suddenly get the error it may mean one of the following:

1. Something fulfilled, the connection;

2. The Vpn Contivity switch where you were trying to connect to plan your client was down or timed out;

3. Your local Isp did something that interrupted your network relationship long adequate for the Vpn Contivity switch to recognize your client was not responding;

4. The Vpn Contivity switch that you are linked to has either logged your relationship off or the Switch is no longer responding, or a gadget that does not support Ipsec Nat Traversal is causing the relationship failure.

Action(s):

1. Try re-establishing the Contivity relationship by clicking the connect button. If this works, the relationship was probably lost due to the Idle Timeout configured on the Contivity Vpn Switch. If no data is transferred through the Contivity relationship for a long period of time, 15 minutes or more, the Contivity Vpn Switch automatically disconnects the connection;

2. If you were unable to successfully re-establish the Contivity Connection, the dial-up relationship may be preventing data from traveling between the Contivity Vpn Client and the Contivity Vpn Switch. Hang up the dial-up relationship and reconnect before you try to re-establish a relationship to the Contivity Vpn Switch;

3. If you are still unable to connect to the Contivity Vpn Switch, open a Command Prompt and try pinging the Contivity Vpn Switch using the host name or address that you specified in the Destination field.

(a) If you receive a "Destination Unreachable error" there is a routing question at the Isp.

(b) If you receive a "Request Timed Out" error message, the Contivity Vpn Switch is probably not available, and you should touch your Network Administrator.

4. If you keep getting this message and are unable to connect, then it may indicate that the Contivity Vpn Switch is unable to describe with the client because it is behind some kind of Nat (Network Address Translation) device. Nat (Network Address Translation) Traversal allows a amount of devices on a secret network to way the Internet simultaneously without each requiring its own external Ip address. Most hotels and airports that provide Internet connectivity use Nat to connect to the Internet.

Q6 Error Message: Cannot Alter Routing Table

Cause: Message means the you the user, an application on your machine, or your Isp attempted to convert the routing table via an Icmp redirect effort and it was not successful. The client detects the effort to make the change, determines it's a security breach and shuts down the client's connection. Any time you make a Vpn connection, you cannot convert the routing table, because the Vpn Client views this as a security risk and you will get disconnected.

Some applications need an Icmp redirection in order to work such as a game or other third party software.

Action: If you receive this error and cant connect due to an Icmp redirect attempt, shut down any other applications you are using which may be causing the Icmp redirect attempt. If it is the Isp that is doing it, you will need to block the Icmp redirect request. You can recognize that Icmp redirect has occurred, by seeing a message saying there has been an Ip address routing table change.

Q7 Error Message: Receiving Banner Text Information

Cause: Message means you are experiencing a Banner Sock issue, and will see a window displaying the "Receiving Banner Text" message and then gets disconnected.

Actions:

1. Disable the firewall completely to test. This is a port 500 issue and often means that the you have a personal Firewall that is blocking port 500 or you have a router that does not support Ipsec pass-through, and the you are connecting to a Vpn switch that does not have Nat Traversal enabled.

2. If using wireless, temporarily remove Wireless from the photograph and focus on the Ethernet card. Check the Ethernet card speed and duplex parameters and then make sure that the hub, switch, or router that is on the other end has the same parameters. If not, the Vpn relationship will drop as the link goes up and down, or due to a large amount of errors on the port from a duplex and or speed mismatch.

3. Firewall that blocks the connection, such that theory will crash. (This will rarely happen) Nsdf (Norton Symantec Desktop Firewall) and Nspf (Norton Symantec Personal Firewall) can do this though, if you do not trust the Ip address of the Vpn connection.

If you do not trust the Vpn address of the Vpn client, the firewall will cause you to crash. In your Internet browser click on "Tools > Internet Options > Security > Trusted Sites > Sites" and add the destination Vpn address(es) to your trusted sites.

Q8 Error Message: You already have the maximum amount of adapters installed

Cause: You may have installed to many virtual adapters in your Ip Stack

Actions:

1. remove any unnecessary adapters;

2. Create multiple boot scenarios disabling the adapters that are not required for that function;

3. You may also get Banner Sock errors on Win 95 & 98 units with this condition;

4. For more information, see this Microsoft article: Kb217744: Unable to Bind Protocols to More Than 5 Network Adapters (copy and paste into the hunt tool bar > enter).

Q9 Upgrade Errors: The following are some errors that may occur when trying to upgrade / setup the Nortel Vpn Client 4.65

Error (1): Failed to get Registry key value for Nt_Ipsecshm

Cause: This is caused because an foremost registry key that cannot be found in the theory registry.

Actions:

1. Uninstall and Reinstall the Vpn Software

Error (2): Login Failure due to: Driver Failure

Cause: This is ordinarily caused by either not having Admin proprietary to the Pc or by trying to install/use a Nortel Vpn client that predates the operating system.

Actions:

1. Ensure that you have admin proprietary to the Pc.

2. Update/Install the most current version of the Nortel Vpn client.

Error (3): Create socket failed with 10048.

Cause: This question ordinarily will occur whenever you have other Vpn client software installed on the system. The most noted conflicting clients are: Aol, Cisco Vpn Client(s), Ssh Sentinel and Pgp.

Actions:

1. Removing these clients will in most cases, conclude the issue.

(3) Vpn Modems Troubleshooting Guide

Q1 Are Cable Modems supported for Vpn Access?

Yes, you can use cable modems for Vpn access. However you must be aware of the following conditions and be able to work within them:

*Some cable modems need that you log into an Nt network to get authenticated.

*Some cable modems use a client similar to the Extranet Client for Vpn and both will not run at the same time.

*Some cable modem Contracts/Acceptable Use Policies specify that you cannot use them for firm purposes or they want to fee you other fee to use them for firm purposes. Make sure you read your ageement thoroughly.

*Your Cable modem provider is your Isp. Please see the Vpn-connection-guide.html">Isp Troubleshooting Guide for more information.

Q2 Why does my modem seem to Perform erratically?

Always make sure that you do not let the operating theory elect a generic modem. If required, go to the acceptable web site for the seller of the modem and get the updated Inf file so that the permissible parameters are configured for the modem.

Q3 Why do I all the time seem to get a slower relationship speed than others with the same modem?

1. all the time check the modem configuration to verify that its maximum speed has been selected.

2. It is common when auto-installing modems that the highest speed is not superior automatically.

3. Do not check the box that says run at maximum speed only.

Q4 I plugged my modem into the phone line at the hotel or customers office and now it does not work.

Always make sure that the phone line you are plugging into when visiting somewhere is an analog line not a digital one. Plugging into a digital line can constantly damage your modem, requiring a transfer unit. To avoid these situations please touch the local site phone support personnel.

Q5 Why cant I get a 56Kb V.90 relationship from some locations that I go to?

Here are some of the reasons why you might not get a 56K connection:

1. You are settled more than 3 ½ miles from your telephone companys central office (Co).

2. A Slick or Subscriber Loop theory is used in your area.

3. You are calling from a digital Pbx system, which creates a Digital to Analog conversion and then an Analog to Digital conversion.

4. Your line contains digital pads or Robbed Bit Signaling (Rbs), which can degrade your relationship speeds.

5. Your wiring may be of poor quality.

6. Your modem's firmware may not be up-to-date. Check that your modem has the newest V.90 code installed with all the patches from the vendor's web site.

Q6 Why cant I get higher speed on my 56K v.90 modem into some Nag?

Here are some possible reasons:

1. A 56k v.90 modem is asymmetric by produce where download speed can be as much as 56k but upload speed will be up to 33.6bps. For 56k to work, there must be only one analog-to-digital (A/D) conversion in your local phone loop. Thus when modems at both ends are analogue, 56k speeds will never be achieved as most Pstn exchanges run digital routing between the exchanges.

2. Some Nag sites use analog phone lines with Cisco and acceptable 56k modems, and most Pc's dial-ups use a similar modem. between the two modems, it limits the download speed to about 33.6kbps maximum.

3. Also, many users might touch lower relationship speeds due to other reasons, such as more poor line quality. These factors will also contribute to the ability and speed of the line.

(4) Vpn Isp Troubleshooting Guide

Q1 If you are getting the message "Unable to conclude the Ip address of the Remote Server. Verify the Host Name in the destination field is correct." when trying to connect with the Extranet Client.

Try pinging your destination name (Example: Vpn.something.com) and if it fails call your Isp to make sure that their Dns is functioning correctly.

Q2 Why do I get No Domain available when dialing my Isp?

On your Internet aid Providers (Isp) dial connection. Right click the mouse and elect the properties button. Click on the Server Type tab and make sure that the Log On To Network box is unchecked.

Q3 Why do I seem to be running moderately through my Vpn connection?

Try turning off the Software Compression option on your Internet aid Providers (Isp) dial relationship as the Vpn client has it's own compression. Right click the mouse and elect the properties button. Click on the Server Type tab and uncheck the

Q4 I keep getting busy signals when trying to connect to my Isp, what should I do?

Contact your Isp giving the numbers you are trying to connect to. Many times you will find that can give you an alternate amount not published yet that will work just fine. If not you may need to find other Isp that provides great service.

Q5 When configuring the dial icon for my Isp what should I put in the Dns/Wins settings?

Your Isp should provide you with the Dns/Wins settings of your dial connection. Most only give you Dns, in this case just leave the Wins settings blank.

Q6 Why when I load the Extranet Client on my Pc and Winpoet is installed on my machine it crashes or does not work properly?

There are issues running Winpoet software on the Pc with the Nortel Extranet (Vpn) Client.

To repair your system, boot in safe mode and uninstall the Winpoet Software.

A simple explication is to setup the Linksys Befsr41 hardware router. It has a firmware Pppoe connector, which eliminates Winpoet from the Pc and provides the added advantage a Nat firewall with the ability to hook up to three other Pcs.

A second option is to find a Pppoe Client that does not interfere with Vpn Clients.

What is Network Security? Simplified Definition

First of all, what is a network?

The network we refer to here is the computer network, which has so many definitions from too many sources either on the internet or elsewhere. Naturally put, a network is the inter-connection of cables and other communications media, connectivity equipment such as switches and routers, electronic devices such as computers, printers, scanners, plotters, etc., for the purpose of sharing data and resources.

SECURITY

Whoa! Now, that doesn't sound straightforward at all, does it? Alright, let's give it a second try...

A Network is the inter-connection of communications media, connectivity equipment, and electronic devices for the purpose of sharing data and resources.

Now, that wasn't too hard, was it? And here's the second question...

What is Security?

This one is easy, as the word security means protection or safekeeping, protection or well-being.

So Naturally put, Network Security refers to any undertaking designed to protect the network.

Why do we have to protect or "Secure" the network?

We need to protect the network because there are constant threats against the "resources" we share in the network. These could be considerable facts or data about our employees and clients, or more importantly about our products or businesses. Most of these threats come in the form of:

* Viruses, worms, and Trojan horses
* Spyware and adware
* Zero-day attacks, also called zero-hour attacks
* Hacker attacks
* Denial of service attacks
* Data interception and theft
* Identity theft

In order for us to fully understand what "Network Security Solution" is all about, we must also understand how Network Security works. Because there are a variety of threats, there is no single solution. We need complicated layers of security, so that if one fails, the attacker would have to deal with the next layer.

Network Security Systems are ordinarily composed of many components of both software and hardware which are designed to work together to heighten security and minimize maintenance. The software must be relentlessly updated to preclude from new threats.

These components include:
* Anti-virus and anti-spyware
* Firewall, to block unauthorized entrance to your network
* Intrusion prevention systems (Ips), to detect and block attacks
* Virtual private Networks (Vpns), to provide obtain remote access

Cisco and Microsoft Network Certification

The popularity of networking vendor certifications has continued for 10 years now with millions of network engineers attaining the Microsoft Certified Professional Designation (MCP) and hundreds of thousands obtaining the Microsoft Certified Systems Engineer (MCSE). In addition hundreds of thousands have earned Cisco Certified Network Associate (CCNA), Cisco Certified Network Professional (CCNP) and Cisco Certified Internetwork Expert (CCIE) designations. Developers often select the Oracle or Microsoft programming certifications. There are alot of benefits whether you select the Microsoft or Cisco network vendor certifications. The benefits include salary increase, job promotion, learning new skills and improved marketability.

microsoft security essentials

The Cisco CCNA wireless network certification as an example, is a great way to learn new wireless networking skills if you have no on the job experience. The most popular networking certifications today include MCTS, MCITP, MCSE, CCENT, CCNA, CCNP, CISSP, MCAD and MCSD. The Microsoft Certified Technology Specialist (MCTS) and Microsoft Certified IT Professional (MCITP) are the basic Microsoft networking certifications that have replaced the older MCP designation. The MCSE is comprised of additional more difficult exams focused on advanced network administration, troubleshooting and design topics. The Cisco Certified Entry Networking Technician (CCENT) is their entry level certification and required before attaining any additional certifications. CCNA is popular and covers basic networking topics such as routing, switching, protocols, osi model, wireless, troubleshooting and security. The CCNP is much more difficult than the CCNA and focused on similar topics with increased depth. The CCIE certification is the most difficult that Cisco offers with a written and lab exam. Having a certain number of network engineers on staff with the CCIE certification is a prerequisite for companies wanting Cisco Gold Partner status.

MICROSOFT SECURITY

Microsoft developer certifications including the MCSD.NET developer course while the MCAD covers programming and software engineering topics. The Certified Information Systems Security Professional (CISSP) is a Cisco security certification that has become increasingly popular with the increased complexity of security design and companies wanting improved security on the internet. The process most often involves the use of study books, courses, practice exams and forums. Vendors publish study guides that describe what topics will be tested and the exam format. Practice exams with a question and answer format using similar questions found on the exams have been proven to work however best suited to those with experience. Candidates must register with Prometric (Microsoft) or Pearson VUE (Cisco) as the approved vendor testing sites.

Secret Article Marketing Tips for Network Marketers

Article marketing tips, the best kept secrets for getting traffic, leads, sales, and new sign ups. A solid marketing plan for network marketing, MLM, or any and all online businesses

Finding The Right Keywords

ESSENTIALS LATEST VERSION

One of the most important article marketing tips to remember is the importance of using the right keywords. You must select keywords that are relevant, high traffic keywords, low in competition, and have high commercial value. The best way to accomplish all of these parameters is the use of keyword research tools, either free versions, or paid versions. Free/paid versions of research tools can be found on the Internet by doing a simple search for keyword research tools.

With keyword research you want to get highly targeted traffic, people that are ready to buy, and are searching for the content in your article. You want to choose keywords that also have a fair amount of traffic (no fewer than 100 searches per day) and are not so highly competitive that you can't compete. The goal is to beat out the competition and get your article on the front page of Google. The front page of Google is the Holy Grail for keyword research.

Finding out whether or not your key word has high commercial value can be as simple as doing a Google search for your keyword and noticing whether or not there are paid ads on the right of the page. The more paid ads on the right of the page the higher commercial value of your keyword. The more paid ads the better.

On Page And Off Page Optimization

Other great article marketing tips. On page optimization is essential to ensure that the search engines can access your article and determine its relevant content. To accomplish this using your keyword in the title of your article is a must, also the first and last paragraph of your article, and several times in between the first and last paragraph in the body copy. Also the keyword should be underlined, italicized, bolded, and put in quotes at least once throughout the length of the article.

Off page optimization can be greatly enhanced by submitting your article to high authority web sites for page rank and getting back links to you article. Some high authority websites are, EzineArticles PR 6, Squidoo PR 8. etc., Submitting to these sites gives you page rank over other article marketers using the same keywords.

For back links to your article, the more sites you submit to, such as blogs, forums, and article directories, the more back links you will get. One of the most important "article marketing tips" is, all other things being equal, he who gets the most back links wins the article marketing game.

Article Marketing Tools

Tools are a must if you don't want to spend most of your waking hours finding the best keywords, submitting articles, and getting back links, the more tools you have the less work you do to get these back links. You can find quite a few free tools on the net with a simple Google search for the tool that will perform the function which you are trying to achieve. If you have a small budget you can also purchase tools to automate the repetitive work of back linking. I would suggest using the free tools before buying anything. as you need to have the knowledge of what you are looking for in a tool before you lay out your hard earned money. Tools can help you automate most of the repetitive work, and free you up to do the more important work of creating informative, helpful articles that draw people to your site or business.

Be Consistent

One of the last "article marketing tips" is; stay consistent. Don't be disappointed if you don't see results immediately, expect to have a lag of 2 to 3 weeks before you see results after posting your article. Write and post articles daily, if possible, or at least several times per week. The fruit of your work will multiply over time, and once you are out on the search engines there is a cumulative effect to the amount of leads you will receive. The secret to article marketing is longevity, articles exist in perpetuity, and the great thing is, unlike paid advertising, the cost of these leads is next to nil.

Secret Article Marketing Tips for Network Marketers

Article marketing tips can ad many leads, sales, traffic, and sign ups to your business. Depending on the number of articles you write, you can ad hundreds of leads per day with well written, hard hitting, informative articles. The sky is literally the limit when it comes to article marketing leads. Insure your spot as a top earner in your network marketing, MLM, affiliate marketing business with the wealth of information and training provided at My Lead System Pro. Start today with an article marketing plan and virtually insure an endless stream of free targeted leads for your business for years to come.

The ISO Network Management Model

The rumor on how Disney uses Network Management. When the temperature rises on the park grounds at Disneyland all the prices of the beverage vending machines automatically goes up by 10% to fully capitalize on consumer demand. I believe that is an old Information Technology rumor to explain how network management works... at least I hope it is a rumor.

Why Network Management is important.

MICROSOFT SECURITY ESSENTIALS LATEST VERSION

More and more organizations depend on their networks. Business' the depend heavily on the status of their networks must have network management tools as they grow. If a network dependent business such as ebay, Google, Yahoo and many others go down for even a few minutes, they can loose literally hundreds of thousands of dollars in sales and even a small piece of their customer's confidence which could in turn affect the value of their stock. When every second of network time counts the system must be monitored continuously. The most cost effective way to do this is to use an automated network management tool.

Network Management Standards

The International Organization for Standards (ISO) addresses the five major functional area of the Network Management Model as performance management, accounting management, configuration management, fault management and security management.

Performance Management

Performance management is monitoring, assessing, and adjusting the available bandwidth and network resource usage in order make a network run more efficiently. Performance management is a very important part of the network management model particularly to the business and/or organization that wants to streamline their network's performance. SolarWinds is a great tool for performance management.

Accounting Management

Accounting management monitors and assesses the usage of data and/or resources for the purpose of billing. This aspect of the network management is by Internet Service Providers to bill customers for the resources they use.

Configuration Management

The configuration side of network management is for tracking the hardware and software versions on the network to identify their effects on the network's operation. An example of this is Microsoft's System Management Server (SMS) which has the capability to monitor, manage and track every piece of software and hardware on a given network.

Fault Management

Fault Management is what most people think of when they think of network management. The purpose of this area of network management is to detect, log and alert the system administrators of problems that might effect the systems operations.

Security Management

Security Management deals with controlling access to resources and even alerting the proper authorities when certain resources are accessed. In the same way that a network manager can be paged or emailed when a resource goes down, network management systems can be used to send messages when certain files, servers or routers is accesses. Intrusion detection systems such as Symantec's Intruder Alert have this security management capability.

There are many products that support some or even all of these areas of network management. What most network management systems have in common is their use of protocols such as Simple Network Management Protocols (SNMP), SNMPv3, and Common Management Information Protocol (CMIP). There are a variety of Network Management tools ranging from Intuit's Network Management Software to IBM's Tivoli, Fidelia's Helix to AdventNet. Maybe your network management solution does not include a system that increases vending machine prices as the heat rises, but you can definitely find what you need among these and other excellent tools on the market.

Can I add additional applications when starting a conference? When starting a conference you can select the initial application to be launched. Once in the conference you can then add additional applications as needed.
How do I prevent others from joining a conference while I do preparation work? Select Attendee List Only option when creating the conference but leave the list empty. The conference will then only allow the host to participate. Once the conference preparation work is complete, the host then adds you to the conference and they will then be able see the conference in the list and join.
When I click the whiteboard button, a whiteboard does not launch? The whiteboard tool requires that Microsoft Paint be installed on the conference servers. Verify that mspaint.exe is available installed.
How do I set my default for conference start up to always be full screen? From the MetaFrame Conferencing client interface, select Tools from the menu bar and the Options. From there you may define when full screen is used; Always, Never etc.
How do I enable or disable full screen dialog transparency? From the MetaFrame Conferencing client interface, select Tools from the menu bar and the Options. From there you may define whether dialog transparency is on or off.
How do I schedule a conference? Scheduled conferences are managed through your Microsoft Outlook calendar.
How do I schedule a conference without Microsoft Outlook integration? Only instant conferences will be available without Microsoft Outlook integration. MetaFrame Conferencing Manager leverages the Outlook calendar for the central management of all your conferences and meetings.
Is Microsoft Outlook integration required? Microsoft Outlook integration provides the ability to you to schedule conferences ahead of time. There is no requirement for Microsoft Outlook and choosing not to utilize it will not impact the ability or functionality of instant conferences.
What is the custom form for scheduling conferences? Citrix has provided the option for a custom form to be used when scheduling conferences. By using the custom form, an additional setting that defines who besides the organizer may start a conference is available.
How do I access the custom form? The custom form may be accessed in two ways. First you may find a button on your Outlook menu bar. By clicking this, the custom form will open and you can schedule your conference just as you would a normal Outlook meeting. It may also be accessed by selecting from the menu bar File, New, Choose Form and then select the form from the list.
What is the difference between using the standard form verses custom form? The custom form may be optionally used instead of the standard Outlook appointment meeting form.

Using the standard appointment meeting form in Outlook will still allow the ability to start it as a MetaFrame Conferencing Manager meeting.
How do I prevent others from starting my scheduled conferences? By using the custom form, an additional setting that defines which you may start a conference besides the organizer is available.
Is using the custom Outlook form to schedule a conference required? No. The custom form is provided to enable the ability to restrict who may start a conference other than the organizer. Scheduling a meeting through the standard appointment form will not prevent the organizer or other invitees, from being able to start that meeting as a conference within MetaFrame conferencing Manager.
Why does Microsoft Outlook need to be installed on the same server as the MetaFrame Conferencing Manager client? When the MetaFrame Conferencing Manager client launches, it will query your calendar through Microsoft Outlook. A defined Outlook profile needs to exist under the same credentials as those launching the client component. If these requirements are met, the calendar entries in that Persons Outlook will be reflected within the conference list in the client.
Do I have to use Microsoft Outlook on a published server? While Microsoft Outlook must be on the same server as the MetaFrame Conferencing Manager client is published, it does not need to be published or accessed from the server. You may schedule and coordinate meetings with Microsoft Outlook as they currently do. If you want access to the custom form, it will be available through the organizational forms library or by clicking the custom Outlook menu button. See under How do I access the custom form?. The add in menu button must be installed properly in order for the form to work i.e. using a local copy of Microsoft Outlook requires the add in to be installed for the hot button to work
What if my Outlook calendar meetings are not showing up in the conference list? First verify that there are meetings in your calendar for that day. Also verify that Microsoft Outlook is installed and configured with your profile on the same server as the client is published. Will require verification from your MetaFrame administrator. Finally, ensure that you are launching the client with the same credentials as your Outlook profile uses. Again, may require verification from your administrator.
When launching MetaFrame Conferencing Manager, I am receiving a security dialog from Outlook? This is potentially a result of an incomplete installation and configuration of the Outlook custom form. For Outlook version 2000 SP2 and later, Microsoft added a security feature to protect against scripted viruses. This security feature will protect you against malicious scripts. When adding a scripted form or add in, part of the process is to register that component with Outlook to let it know it is not a virus. Unless this step is taken, Outlook will continue to notify you that the script add in is potentially harmful.

Wireless Home Network Security

In order to adequately protect your wireless home network you need to have an awareness of the threats that are out there and what can be done about them. The best ways to ensure your security are by using a legitimate antivirus/anti-spyware program, an effective firewall in your router and setting up wireless encryption on your wireless router.

microsoft security essentials

A wireless network introduces a new level of vulnerability to your privacy through the airwaves. On a wired network a good firewall will stop most Internet hacker attempts and your antivirus program will handle most attempts by trojan viruses to hijack your machine. But now that you've gone wireless your network data is being broadcast through the walls of your house and out onto the street. How do you protect yourself against neighbors who want to surf the Internet on your dime and the geeky teenager with the packet sniffing program next door?

The answer is Wireless Encryption

Before we get into wireless encryption let's make sure your networked computers at least have the basics in terms of protection. Any computer connected to the Internet needs to have:

Antivirus Software

There are tons of scripts, viruses and spyware that can find their way to your computer through emails and downloaded programs which can muck up your operating system and compromise your privacy. A good antivirus program with updated virus definitions will do the trick. This means you have to do more than just purchase and install it. You also have to keep it updated.

Firewall Program

If you have a firewall program such as installed and you take a peak at the logs you may be shocked at the amount of attempts to gain access to your computer from unknown sources. A good firewall program will follow a set of rules to block attempts to gain access or take control over your computer. Many home network routers have a built-in SPI (Stateful Packet Inspection) firewall functionality which you will also want to take advantage of.

Anti Spyware

Spyware actually falls under a different category than viruses. While a virus is designed to do wreak havoc on your Operating System malware is more insidious and seeks to operate behind the scenes undetected. Many spyware programs exist just to collect data about you and your surfing habits and send that information back to who ever launched it as market research information. While your operating system may still function normally you will notice slowness and erratic behavior of some programs over time.

Windows Updates

Microsoft regularly publishes new vulnerabilities that have been discovered in their operating systems and patches needed to fix them. Turning your Microsoft updates to automatic will make the process of keeping your system updated almost unnoticeable except for the occasional forced reboot.

Wireless Encryption

So you've set up a home network using all the steps mentioned above to secure it. Right? Good. If you want to go wireless you also need to consider wireless encryption. If you don't you might as well be installing network jacks into the curb on the street in front of your home to give passerby's access to your network any time they want it.

The developers of the 802.11 standard were aware of this threat to consumer privacy early on so they designed a system of encrypting data that makes a wireless network just as secure as a wired network. They called it WEP or Wired Equivalent Privacy. WEP worked fine for a while but the way it was designed combined with increasing computer speeds made it easier to decode and decipher the WEP Key. Once someone in a car out on the street has your WEP key they may as well be sitting in your living room or watching over your shoulder.

As a result of the need for a newer, stronger encryption method WPA or Wi-Fi Protected Access was developed. Not only is WPA more secure it's more user-friendly. A plain text pass phrase is all that's needed to secure your devices. The ugly hexadecimal keys of WEP are gone. The major improvement of WPA over WEP is the patterns of encryption it uses are much more random and the key actually changes according to a time frame you can specify! WPA has a new big brother called WPA2 which uses the advanced AES method of encryption. While WEP can be cracked in a few hours WPA2 and AES has yet to be cracked.

The safeguards mentioned here are all very common and easy to come by. Excellent Internet Security Suites are now available in most electronics stores. Virtually all routers come with built-in SPI firewalls and manufacturers of network devices have made great strides to make setting up wireless encryption on your wireless network as easy as possible. By following the guidelines in this article and technology that's available you should have no trouble securing your wireless home network.
