Terminal Services Idle Timeout

Are the users getting the popup message that

Idle timer expired : Session has been idle over its time limit.
It will be disconnected in 2 minutes.
Press any key now to continue session.

If so then the idle timeout is set somewhere else.

Session timeouts can be set:

On the Connection object

Start–>Run–>tscc.msc–>right-click RDP-Tcp–>Properties–>Sessions tab

On the User object

Active Directory Users & Comp–>right-click the user–>Properties–>Sessions tab

On the Group Policy object

Edit the GPO–>User–>Admin–>Win Comp–>Term Serv–>Sessions


Edit the GPO–>Comp–>Admin–>Win Comp–>Term Serv–>Sessions

The users may not have noticed the popup window, so
check the event log for Application Popup entries.
