SYMPTOMS
When you try to connect a drive that was previously connected to a Distributed File System (DFS) resource, you may receive the following error message:

System error 85 has occurred. The local device name is already in use.

This error message persists for the particular drive letter in that particular Terminal Services session. The same drive letter for other Terminal Services sessions may work as expected. A different drive letter that is not typically used also works as expected. The only way to correct the issue is to restart the Terminal Services-based system.
