A server we manage has a number of people who log in to access it and we've had an issue lately where it will start slowing down then eventually lock out any incoming connections and drop most of the current ones. They will attempt to join/rejoin the server and are given this message: "Please wait for the Terminal Services Configuration" and are left there. The only solution we've been able to manage has been to physically perform a hard-reboot. When attempting from within the server we are able to pull up the menus but after it kicks us out the shutdown process appears to halt.
Any thoughts would be very appreciated!
