Trying to login to a Windows server remotely using RDP local Administrator username and password as credentials, but I get a failure to authenticate. Syntax I'm using is <servername>\Administrator and then the password. I can logon remotely using my Domain admin account, however. So I know RDP is working fine.
User Rights Assignments have the Administrator group as member of Allow Log on Locally and Allow Log on through Remote Desktop Services and Administrator local user is a member of the local Administrator group. Any ideas appreciated.
