Terminal Services and Windows Firewall

Applies To: Windows Server 2008

Windows Firewall is on by default in Windows Server 2008. Windows Firewall helps control which programs or ports can be used to communicate between the server running Windows Server 2008 and other computers on the network or the Internet. To allow a program or port to communicate through Windows Firewall, you need to enable an exception.

If you enable Remote Desktop, Windows Firewall automatically enables the Remote Desktop exception.

When the Terminal Server role service is installed, Windows Firewall automatically enables the following exceptions:

  • Remote Desktop

  • Terminal Services

If you install other Terminal Services role services, Windows Firewall automatically enables other exceptions. For example, when you install the TS Licensing role service, Windows Firewall enables the Terminal Services Licensing Server exception.

When you uninstall a role service from the computer, Windows Firewall automatically removes the exception for that role service.

Important

When the Terminal Server role service is uninstalled, only the Terminal Services exception is removed. The Remote Desktop exception is not removed.

Use the following procedure to view Windows Firewall exceptions.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).

To view Windows Firewall exceptions

  1. Click Start, and then click Control Panel.

  2. Click Security, and then click Windows Firewall.

  3. Click Change Settings, and then, in the Windows Firewall Settings dialog box, click the Exceptions tab.

  4. If the check box associated with the program or port listed is selected, the Windows Firewall exception for that program or port is enabled.

    Some programs only appear in the list when the role service is installed. For example, the Terminal Services Licensing Server program only appears in the list when the TS Licensing role service is installed on the computer.
