I have three machines on my network, two are windows xp and one is windows 7. i would like to have all three machines log a user off if they are on for more than 60 minutes. And I would like this to be applied to the machine not on a per user basis, because I do not want this policy to apply to those users on any other machine. I have installed winexit.scr on one of the machines but the problem is that I cannot change the default value of 10 minutes for the screensaver because that is controlled through group policy, and I cannot seem to find where to change that through group policy on a per machine basis NOT on a per user basis. If I have left out any details I apologize please let me know anything that is needed
