Ok I have about 4 computers on a workgroup and wish to limit access to one of these computers. I would like to be able to create an account on each PC and then log in and have access to the one PC I wish to limit. I have tried to add the computername/username combo to the admin group of the PC I wish to limit access to but that does not work. Is their anyway I can do this without turning my network into a domain? Any help will be greatly appreciated. Thanks, Jesse
