The administrators of our workgroup would like the change the Windows XP power settings (specifically, screen blanking) for our PCs. We have admin access to all machines and the ability to launch a job running as the System account via SMS. As members of a much larger domain, modifying a GPO would involve lots of forms and negotiations, so preferred to be avoided.
powercfg.exe can be used to change the power settings, but that only seems to affect the current user. An existing GPO prevents non-admin accounts from directly using powercfg.exe themselves.
I suppose writing a script that modified each profile in the registry would work if run as System via SMS, but I was hoping for something a little simpler.
