I have not tested this, but there is a setting, that appears to log off
users when the "logon hours expire", perhaps you could use this to enfore
that clients log off.
Computer Configuration->Windows Settings->Security Settings->Local
Policy->Security options->Force Logoff when logon hours expire
If this does not work, you could write a script that logs the user off that
you schedule to run.
Here is a sample script on how to do this using WMI
Set oWin32_OperatingSystem =
GetObject("winmgmts:{impersonationLevel=impersonate,(Shutdown)}").ExecQuery(
"select * from Win32_OperatingSystem")
for each Operatingsystem in oWin32_Operatingsystem
OperatingSystem.win32Shutdown 0,4
Next
Good luck
