I'm runnning at half capacity today, my memory is stuffed.... Anyway, my task is simple. I want to shut down 9 PC's at 4.30 every day. I'm running windows server 2003 and the clients are on a domain runnning xp. I was going to just put a simple batch file as a scheduled task. using: shutdown -s -t 60 but I can't remember if it would work if there was no one logged on (memory is really gone today) or am I best running a script from the server like this What I want is relabilty over neatness of code or simplicty of implementation. I just want 9 PC's of every day at 4.30 with out fail. It's getting on my tits seeing 9 PC's that have been runing over the whole weekend 'cos some silly $*&£ can't bothered to shut down.
