I have one Domain Controller running Windows Server 2016
While adding a group of users to the Active Directory somehow the administrator account password got changed (or maybe even the account got deleted altogether?). I can no longer log onto the server. I tried logging onto the server as one of the users I had created and those accounts are all disabled.
I tried booting the server off of the boot disk and changing the password by typing the following in the command line:
f:
cd windows\system32
ren Utilman.exe Utilman.exe.old
copy cmd.exe Utilman.exe
net user Visioneer password
(where Visioneer is my username and password is my new password). However, I get an error saying the user name could not be found. Thus it leads me to believe maybe the account was deleted? When I try to log in as Administrator it says that the account is disabled.
I cant login to my server anymore. How do I regain access?
