Is there a built-in feature (or perhaps a third party app) that will apply a time quota to the users of an XP box? This is my story: I have 4 kids who share the same PC. The problem is they are always fighting because "sibling1 has been on for 3 hours", or "sibling2 has been on twice and I haven't used it yet", etc etc. It's getting to be a pain in the butt to hear this all the time and I want a way for the computer to be the "bad guy" and tell them to log off instead of "evil dad". What I would like to do is allocate a maximum of, say, 3 hours of login time per person. When that time is reached, it simply logs the user off and doesn't allow them to log in again until the next day (or an admin changes the time limit). It would also be sorta nice if there would be a warning message about 5 minutes before the logoff time. There is a drive space quota but I cannot find anything about a time quota. I even browsed through the policy settings but couldn't find anything there either. A google search turns up nothing too.
