So, I've got a WinXP desktop that i recently updated to SP3... though the problem existed before I did this. RDC was working fine a couple months ago, with a dyndns account and my router setup, and I was accessing it fine while out of town for months. But recently I cannot login, remotely, or even from the same network. What happens is... When I click Connect... it grays out and tries to connect for less than a second, then stops. No error message. It just kind of blips and leaves me with the same dialogue window. I click again and again and it repeats. I do get the appropriate error messages when I turn off RDC on the host and then try connecting. So it seems like the connection is reaching the desktop host, but just not responding correctly. I have tried with two different client computers with the same result. The client is WinXPSP2, RDC 6.0. RDC 5.1 did not work either. I looked at Event Viewer and didn't find anything (at least nothing with a correlating time stamp). I really want to have this accessible when I'm out of town. I saw mention of a RDC problem related to graphics drivers... but I didnt find the actual thread... is their problem similar to mine? I have a Nvidia GF 7900GS.
