I have recently gotten 3 tablets with win7 preinstalled. I can connect them to our school domain which is located on a win 2000 server. The problem is that I can log in from those machines with my domain administrator credentials, but I can't get anyone else to log on. The following message is produced: "You cannot log on because the logon method you are using is not allowed on this computer. Please see your network administrator for more information." I have used these methods: domain\username and email@example.com for the username. When I tried to add a domain user account, I get this message: "the user could not be added because the following error has occurred: the trust relationship between this workstation and the primary domain failed." Any suggestions out there?
