When you connect to a computer that is running Remote Access Services (RAS), you are successfully authenticated by a Windows NT 4.0-based domain controller. However, if you disconnect and then immediately reconnect, you may receive the following error message:
This problem can occur if the RAS client receives a new Transmission Control Protocol/Internet Protocol (TCP/IP) address from the RAS server when you reconnect. The authenticating domain controller does not update its local NetBIOS name cache with the new TCP/IP address of the RAS client, causing the RAS client authentication not to succeed.
