Sorry for leaving out the details (mentioned above by Richard): Both clients (2) are XP SP2, I'm using 2003 on the server with Kix 4.22. When I run the SCHTASKS command manually it works, even on the test user account (no users but myself have admin rights). The SHUTDOWN script (shown in the first post) works fine as well. The only problem is that the RUN or SHELL lines in my Kix file don't seem to create a scheduled task.
Ideally, I would like to be able to launch something that runs in the background at each logon, that would monitor the current day/time and compare against the User logon hours (applied to their user account in AD). If the day/time falls outside of that, log them off. The GPO setting "Force Logoff when Logon hours expire" apparently does not do this and is only intended to block access to resources (go figure, stupid policy title).
