| Scheduled Logoff Fails on Locked Workstation with Active Screen SaverID: Q223408 
 | 
If a scheduled logoff occurs while a computer is logged on, but it is locked and a screen saver is active, then only a partial logoff occurs. The computer is left in a state where it has a blank desktop. Pressing CTRL+ALT+DEL still opens the Windows NT security dialog box.
