Remote Desktop Disconnected - The remote computer disconnected the session because of an error in the licensing protocol.

This computer is the only computer in the office having this problem connecting. We have two servers in our office. Our main server is a windows 2003 server running exchange. Terminal services on this is in administration mode as we do not terminal to this. We have a seperate computer "server" that we have windows 2000 advanced server running. This is NOT a domain controller or backup domain controller, it is just a member of the domain. Up until now we have had no problem with users connecting to the system, but all of the sudden this one computer gives us the above error. It is only this one computer so we actually wiped the computer and installed a fresh copy of windows xp pro and that still didn't fix. I really don't understand why all of the sudden this is happening and only on this one Dell Windows XP computer?
