Hi!
I had this problem when i moved a server from a location to another.
My 2003 server has got two NIC and i used one for the first location and the
other for the second location.
When i tried to connect with RDP to this server i found this problem.
Looking for a solution in Terminal Services Configuration, i've founded it
by authorizing the second Nic to be used for RDP.
The location of the command is:
Terminal Services Configuration
+RDP-Tcp Properties
+ Network Adapters.
