You can configure their domain accounts to have logon time limits and then
configure security policy to force them to logoff after their time
restrictions apply however that will only log them off of domain resources,
not the local computer they are logged onto. If you need to force them to
logoff of the local computer you will need to use something like a screen
saver that can log a user off of after a certain period of idle time or at a
certain time. The Resource Kit offers winexit.scr that can logoff a user
after a certain period of idle time. It also has to be configured to close
applications and if the user is not a local user the registry on the
operating system may need to be modified. Third party logoff screen savers
can be more flexible but are not free.

Another possibility is to configure a Scheduled Task or use the AT command
to force user logoff at a certain time. The advantage of the AT command is
that it can be implemented to a group of computers using Group Policy as a
startup script. Windows 2000 has logoff and shutdown built in but psshutdown
from SysInternals may work better, particularly for Scheduled Tasks where
the account credentials for the user for the scheduled task differs from the
logged on user. --- Steve
