group policy in Windows Server 2008
One of our employees changed the users setting in a group policy which effects the login permissions for Administrators users.
Each time I try to login locally, the following message shown:
You cannot log on because the logon method you are using is not allowed on this computer
All solutions found on the Internet worked inside Windows, but I have only access to the Command Prompt (by using repair wizard)
Any suggestions?
