On XP Pro desktops that have not been upgraded to SP3, I am able to access my NT4 Terminal server using RD 5.1.2600.2180, however when I attempt to access the same NT4 Terminal server from a PC with SP3 and RD 6.0.6001.18000, I am not able to access the NT4 Terminal server and get the following error: "Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again." If I copy the Remote Desktop version 5.1.2600.2180 to the upgraded PC along with the associated DLL, I am able to once again connect to the NT4 server. Does there exist a fix to make the newer version of Remote Desktop connect to the NT4 server without getting the protocol error?
