Terminal Services Session Timeout

We use Terminal Services / Remote Desktop for running specialized software.  Being that the session is often minimized, it is left inactive for extended periods several times a day.  When returning to their session, they find the system locked and are required to enter their password.  The solution to prevent the system from locking out users is to edit the Group Policy affecting those users.  In the GPMC, go to Group Policy Objects, and right click on the appropriate policy and choose edit.  Navigate to User Configuration > Administrative Templates > Control Panel > Display.  On the right change both 'Screen Saver' and 'Screen Saver timeout' to Disabled.Source: Link
