I receive the following error when logging on locally to a newly introduced Windows Server 2012 R2 Standard.
The sign-in method you are using isn't allowed. For more info, contact your network administrator.
Everything in the migration was going well. I ran adprep on the SBS2003. Joined the server to the domain. Installed AD services and promoted the 2012R2 box as a DC. Everything was still going well. I began to decommission the SBS2003 box by removing Exchange. Now I'm unable to login locally to the 2012R2 box as the domain administrator. I can still login locally as the administrator of the SBS box. Any help is appreciated...
