My Secondary Active Directory server has gone dead, and I am installing its replacement now. Everything will be the same, computer name, IP, everything.
The new server is running now, and ADDS installed, but I am hesitating to promote this new server to ADDS, since I am afraid to disturb the current running server. My question is, how do I replace the old domain controller? Should I just install ADDS, and promote it? Or should I do a cleanup? What is the best practice to reinstall ADDS?
I have no backup of this secondary server, since it was dead only within 2 days after operational. Perhaps hardware defect, malfunction or something else.
