Remote Desktop Suddenly Stopped Working

I am running Windows XP SP3 and have been using remote desktop for a while.  The other day it just stopped working.  I accidentally disabled the network adapter on the remote PC while connected to it, obviously I got disconnected.  When I went home and enabled the adapter (same IP, static through router) I can no longer remote the computer.

Firewall Disabled
Port Listening
Remote Desktop Enabled

Cannot even connect over LAN to the machine.  When I click connect the buttons go gray as if trying to connect for about 2 seconds then come back as if nothing at all happened.  No errors or messages, it just does not connect.  If I put in the WRONG IP for Remote Desktop it will throw an error that it could not connect.  I am able to telnet the machine.

Weird. Try running mstsc /admin when you launch the RDP client.

I tried mstsc to connect, with server, port, etc.  It just does nothing and goes away as if launching the connection via the client.  If I add the /admin when running it it gives a dialog showing basically that "/admin" is not a valid parameter.

I have a feeling the issue might be on the client machine. Have you tried it from another? Also, try mstsc /console.

I am able to remote into other machines.  Remote Desktop and Remote Users is enabled.  Could something have happened where it did not properly close the session when I accidentally disabled the network adapter of the host machine during a session?

You're not running Norton products on the affected machine, right?

run "qwinsta" from the command line. You should see the RDP server listening on a port (3389 unless changed). Do you have that line? Is there another program listening on the same port?

I checked that it is listening on the port I specified, not 3389 anymore.  I tried connecting from 2 different computers on LAN (with my port in there of course).

Terminal Services Client 6.1

NOD32 - with web filtering disabled.

Sometimes when you disable the Web Filtering, it can "stick" your ports. Try disabling the service for a few minutes, or even uninstalling NOD32 to eliminate it as a variable and then reinstalling.

Formatted, re-installed Windows XP.  Everything was working fine with RDP until I installed Adobe Photoshop CS3.  With CS3 installed RDP does not work and went back to the exact same error.  Does that make sense to anyone?

I was experiencing the same problem as you. After much searching I found the following two links.

It seems the problem was caused when I installed the latest version of Nvidia Drivers. I didnt have any of the errors they mention seeing in the event viewer however when I uninstalled the video drivers my remote desktop started working. I dont know if this will fix your problem but I thought it would be worth mentioning.
