I am running windows xp, and windows server 2003 as my server, and I have no problems using RDP for my systems except 1 PC that I can't RDP into. I made sure that the firewall settings are fine, so it's allowing RDP port 3389, remote assistance and I compared all the services with a PC that is working and all the services are fine.
I just get the generic error message:
"Remote Desktop can't connect to the remote computer for one of these reasons":
1. remote access to the server is turned off
2. the remote computer is turned off
3. the remote computer is not available on the network
