Hi Everyone
A few months ago our DC got infected with ransomware. We setup a new server two or three weeks ago, configured it as a DC (DC01) and transferred all the FSMO roles to the new DC (DC01). DCDIAG was clean on DC01. We then demoted the infected DC and when we tried to log in via the local admin, we got a "The User Profile Service service failed the logon". I added another user to the localgroup administrators, but get the same error. I wanted to log onto the server to fully uninstall Active Directory and DNS from the server.
Can I just switch off the server completely or is there a way to see if all Domain functionality works except for dcdiag.exe?
