I have a Server 2003 Ent SP2 64bit that I’ve been connecting to for months using what I think is properly called Remote Desktop Administration (NOT Terminal Services). Suddenly, it stopped working and when I try to rdp into the server (from a LAN computer) it says “This computer can’t connect to the remote computer”. I have many times attempted to turn off and back on Remote Administration from My Computer > Properties > Remote but to no avail. I haven’t even the slightest idea where to start looking for why this could be happening. The only thing which I can think of happened the same day is another server on our network (this one is the SQL server) started acting up and we rebooted both servers. But other than that nothing changed. Can anyone give me some insight as to how to diagnose this issue?
