Remote Desktop – Preventing Unwanted Automatic Log Off

I think your next step should be to isolate the problem. It could be the network or Windows, so right now I think the question is about troubleshooting technique. I would start with running a constant ping to the machines you are RDPing to to see if there is packet loss. Then troubleshoot "up" or "down" from there.

If there is packet loss, go "down" and start looking for the network problem. You could also be running a couple of pings at the same time -- one to the servers, one to the router at the same time etc. So this way if it is a network problem, you might be able to see which hop it is at. Also, you didn't mention if both the public and VPN users are in the same location, if they are not, than the network problem would probably not be at the user end.

If the ping is fine and there is no packet loss when they get disconnected, than I would start looking at the server itself. You could also check the event logs while the ping is going as well to be proactive about the problem.

The command I was looking for is:

tscon 0 /dest:console

which ends the current rdesktop session and reset the user as logged in! Found after days of research (and hours after posting here...)
