Windows Server 2016 administrator username

windows-server-2016

I set up a domain and AD on the server. I was playing around with setting group policies for the computers joining the domain and accidentally set interactive logon on the server instead of the computers joining the domain. So now I can't login to the server because it's asking for username and password. I tried to login as .\Administrator and password but it won't login.

What is the default username for Windows Server 2016 so that I can login in the local admin account?

Domain controllers don't have a local accounts database once they become domain controllers; the .\Administrator user doesn't really work in that case (except when in directory services restore mode, which you don't want).

Instead, you'll need to log in using a domain user with the appropriate authorization; that local Administrator user should have been converted to a domain user if this was the first domain controller in the domain.
