I need to restrict my users to only be able to login on 1 machine at a time. Does anyone know how I can go about doing this in Windows 2003 Server? Restricting these users by limiting them to a certain machine is not an option since these users float from computer to computer. And I can't use Microsoft LimitLogin utility since I have to modifiy the schema or any other third party application. Does anybody knows a way to do that through GPO or Vbs.
