Well, no offense but you are doing something seriously wrong. What you might want to do is look into the corporate version of WinXp, the systme doesn't do lockouts when used in that configuration - it was specifically designed to avoid the problem in large production environments with a lot of changout. Like yours. As for the rest of it, I am not going to comment much because I don;t have any information on your situation - but your problem is not one I have seen or heard of in the hundreds of WinXP systems that I or my partners are involved in on a constant basic through our consulting - if XP had a tendancy to lock out like that my beep would be overheating and I would be a wealthy man. So if it's a constant problem for your company, then I suggest you look for the cause of it ... cause it isn't a common problem.
