Joined the domain as the administrator in Windows 7 in my initial setup of the PC with no problem. When I tried to log in to the domain as one of the users on the domain to set up the PC on the end users side, I could not log in. I received the following error message: "You cannot log on because the method you are using it is not allowed on this computer. Please see your network administrator for more information." I can log into the domain with my Administrator user name and password that was originally used in the setup. I can log into the domain with the end user in Windows XP, I do not get this error with Windows XP I have tried to go through the local policies - user rights assignment - Allow logon locally. But once I open "Allow logon locally", the "Add User or Group" "Remove" are grayed out, I cannot adjust any settings. Any suggestions or ideas. Thanks in advance.
