Windows NT Resource Kit includes winexit.scr
functions like a screen saver. Winexit can be configured and tested on the
Screen Saver tab of the Display Properties dialog box in Control Panel. You set
the number of minutes of inactivity allowed. There is a Force Application
Termination checkbox which if selected will have the system close all running
applications regardless of their current state. Ouch! if data is unsaved.
Hopefully you have word processors and other applications configured to
periodically save data. You can chose to have the user logged off 0 - 999
seconds after the inactivity limit has been reached.
There is a configuration problem. You have to grant the users Set Value and Create Subkey
permissions for the following registry key:
The other problem is that there are lots of ways for users to disable
the screen saver.
A commercial alternative is the utility, NetOFF which has the
additional capability to automatically saves user's open files and closes open
Another commercial alternative is the utility, Screen Pass
