SYMPTOMS

Consider the following scenario:
  • You use the Terminal Services Gateway (TS Gateway) role service on a computer that is running Windows Server 2008. You allow the authorized remote users to use the TS Gateway to connect to the terminal servers in your internal corporate network or in your private network.
  • You use Active Directory security groups to control user rights in Terminal Services resource authorization policy ("TS RAP" policy).
  • A terminal server and the TS Gateway are in different domains or in a disjoint namespace.
  • You disable communication to the TCP port 445 on the terminal server or on the firewall.
In this scenario, you still cannot connect to the terminal server through the TS Gateway by using the fully qualified domain name (FQDN) of the terminal server after you install the hotfix 967933. Additionally, you receive an error message that resembles the following:
Remote Desktop Disconnected: Terminal Services Resource Authorization Policy (TS RAP) is preventing connection to the remote computer through TS Gateway, possibly due to one of the following reasons:
  • You do not have permission to connect to this remote computer through the TS Gateway server.
  • The name specified for the remote computer does not match the name in the TS RAP.
Contact your administrator for further assistance.

CAUSE

After you install hotfix 976933, you can connect to terminal servers in the disjoined namespace through the TS Gateway by using their FQDN name. However, this hotfix introduces an additional requirement to create a connection. This requirement is that the TCP port 445 must be enabled between the terminal servers and the TS Gateway. Therefore, the error occurs when the TCP port 445 is disabled between the terminal servers and the TS Gateway.

WORKAROUND

Workaround for Windows Server 2008

To work around the issue, use one of the following methods:
  • Use the NetBIOS name of the terminal server to create the terminal server sessions.
  • Use the TS Gateway managed groups instead of Active Directory security groups to configure Terminal Services resource authorization policy ("TS RAP" policy).

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

When port 445 is blocked on TS, RAP checks for a resource whose domain NetBIOS of TS is not a correct prefix of its domain FQDN. The checking process takes around 30-40 seconds to complete and then the following result occurs:
  • The checking process fails if this hotfix is not installed and the hotfix 967933 is installed.
  • The checking process succeeds if this hotfix is installed.
Note Port 445 is for file and printer sharing.
