How do I Block Skype in a Windows ISA 2000 Server?

Block chat services on an ISA 2000 server.

Internet Security and Acceleration (ISA) servers provide Microsoft network administrators with the ability to control Internet usage. The network administrator can block websites, applications and even restrict the time a user can access the Internet. Skype is a chat and messaging software that you may want to block for users on the network. When you block Skype on the ISA 2000 server, users are unable to connect from the installed software.

Instructions

1. Click the Windows "Start" button and click "All Programs." Click "Administrative Tools" and then click the "ISA Management" shortcut to open your ISA server console.

2. Click the plus sign next to the "Servers and Arrays" icon to expand a list of options. Click the icon labeled "Client Configuration." In the list of options in the detail section, double-click "Firewall Client" to open a new configuration window.

3. Click the "Application Settings" at the top of the window. In the list of applications, click the "Skype" program. Click "OK" to save your settings.

Tips & Warnings

• It takes several hours for the configurations to populate across a large network. The new firewall settings take effect the next time the user attempts to connect to the ISA 2000 server, but other users won't see the update for several hours after you change the configurations.
