We had an issue on a Win2K3 server yesterday where nobody could connect (not even from a console) We only have the admin-mode terminal services enabled. From a different PC on the same network, I checked Terminal Services and there was a list of RDP#xx sessions that had a status of "Down". Right-clicking any session and choosing "reset" generated an error:
"The requested operation cannot be completed because the Terminal Connection is currently busy processing a connect, disconnect, reset, or delete operation."
We ended up restarting the server to clear these sessions; but nobody could quite figure out how that problem occurred in the first place.
My current 'guess' is a problem we have with disconnected sessions. For example, we have a user that leaves his work (vstudio/mssql studio/etc) open and just clicks the 'X' rather than logging off the RDP session. There have been times when his disconnected sessions go 12 days before he logs back in.
Will these long-running disconnected sessions cause the error we were receiving that subsequently required a reboot? Any other suggestions as to what would cause that fault?
