I am unable to close some remote desktop connections without rebooting the server. If I highlight them and select disconnect I get a message that the 'handle is invalid'. Anyone have an idea on how to manually close a session?

From the server, do this – When you hit your Max connection for RDP C:>query session [Enter] C:>reset session 1 [Enter] C:>reset session 2 [Enter] Then you can reconnect via RDP now.

Thanks for responding to this question. In following your advice, I was able to query the sessions and run the reset. However, I backed off doing the reset when I got the message that áll sessions using this protocal will be reset'. I was concerned that all the valid users who were actively using connections would be booted off also. If I do this reset, will it kill just the session I entered? Thanks again for you input.

I believe what JackR meant when he said C:> reset session 1 [enter] was C:> reset session <enter the session number you wish to kill here> [enter] That how I read it so if correct you will only be killing the individual session not all the sessions. Tim

thats right, only that session.. session 1.. would only kill that person connection.

Thanks for confirming this. I have entered the following command: reset session RDP-Tcp#236 in the command window. The screen looks like it just hangs. I get no response and eventually have to do a CTL/C to close the screen. The session still shows as connected. Am I doing this correctly? If so, any other ideas? Thanks for all your help.
