Terminal Services allows access, But not allowed at Console.

[AndyH]

I can open a terminal services session to a Windows Server 2003. Then
from that session I can log into the file system on another Server
2000. No problem.

However if I use the console of the Server 2003 directly, and attempt
to log into the Server 2000 it fails with invalid login attempt.

Both theses servers are on the same domain, and report to a third
Server 2003 as the domain controller / active directory.

Any idea why access is authenticated through terminal services, but
blocked when direct access is attempted?
