Hi
I have a server running 2012 r2 which was a domain controller which i have had to restore from a backup as it failed.
when it failed i manually removed it from the domain as i did not think it would come back online.
once i got it back online i did a force removal from the domain so that i could add it back in again (force removal needed as i had already manually removed it from the domain)
now when trying to install Active Directory Domain Services I get an error saying that the operation could not be performed as the server requires a re-boot.
i can add other roles without any problems.
does anyone have any suggestions on how to resolve this?
