Hi there. I work for School District 15. I just moved 25 computers running XP to a new location. No Internet there. All computers were on a domain and on Active Directory, but since putting them on a workgroup everyone of them shuts down every 2 hours. Says it is caused by NT Authority. I did some research and found that it is probably caused by some script on the computer that runs and looks for the old NBSS domain or AD. How do I get the computers to stop shutting down? The new location does not have Internet for a few months.
