I have 4 pc's in a manufacturing plant all XP and all set up in a workgroup. The owner wants the users to login once in the morning and then it should stay logged in all day. Currently it loggs out if not being used after a set amount of time by default. How do i set it to stay logged in until they tell it to log out. Not that it matters but any of the 15-20 people on the floor should be able to go to any of the 4 machines and do thier thing as they are all identicle.
