I'm working for a small university and we're looking for a program that will automatically shutdown the computers in our multimedia classrooms at a certain time. I've already done some searching around sourceforge and a few other sites but I haven't been able to find any free software that will shut the systems down without having a user logged in. All of our multimedia computers run XP 32bit. Could anyone recommend a good program to accomplish this task? Free would be preferable, but we need something that works so if we have to pay we will.
