I have a machine (which is not the domain controller and I have only remote access to this machine) on a domain X. I tried to promote this machine as a domain controller (domain name Y), during which this machine got disjoined from the domain X. I had logged in as a user from domain X when trying to install AD on this machine. After the installation and reboot I could no longer login as this user.
Which user should I use to login to this machine after installation?
I don't know the local administrator password, so can I create another local user (add it into the Administrator Group), and use this user to access the machine after installation, but I am completely new to setting this up.
