If you can't find the way to do this using google (I didn't try, but I don't think I can, because I lack the necessary basis on server and network management) it's time to ask your boss to send you to some 'Manage a Windows 2003 server' and a 'Manage a network through a Windows 2003 server' course.
Until then, it seems best to visit the PC's, ask the user to login for you and change the energy saving settings yourself (either via the control panel screen or via a .reg file).
i am looking for a script where i can shutdown all the pcs in a lan in an organization when the system is idle for more than 2 hours through group ploicy.
please provide any batch file or shell script or vbs script to run from gp.
if any know it plz explain me it in brefly (steps)
