Newbie Qustion On Win Server 2008??

[ICTCity]

OK, so now I'm asked about How can you remove Active Directory from a domain controller and make it a standalone server again?
i know that i should lunch dcpromo and uninstall it but do i have to do it to the both domain controllers on my network or just one?

Here you can find a complete explenation:

Anyway, open domain and trust and remove the "secondary" server (DELETE / DEMOTE / REMOVE).

Then, do the same thing on the "first" DC.

You can use DCPROMO on both servers, it's up to you.

If you have 2 servers, you have to demote BOTH starting from the "secondary".
