Consider the following scenario. You use the Terminal Services Gateway (TS Gateway) role service of Windows Server 2008 to allow authorized remote users to connect to resources on your internal corporate network or on your private network. Additionally, you use the Active Directory security groups to control user rights on the resources. In this scenario, when a remote user tries to connect to a resource through TS Gateway from an external client computer by using the fully qualified domain name (FQDN) of the resource, the remote user may be unable to connect. Additionally, the remote user may receive an error message that resembles the following:
Note This problem does not occur if the remote user tries to connect to the resource by using only the NetBIOS name of the resource.
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:
This problem may occur if the Domain Name System (DNS) name for the domain differs from the NetBIOS name. For example, the DNS name for the domain is domainname.com. However, the NetBIOS name is TSNetBiosName.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.
Note This problem does not occur if the remote user tries to connect to the resource by using only the NetBIOS name of the resource.
