Remove Orphan Active Directory Domain Controller

[Eduardo Sicouret]

Hello,

I had problems with a corrupt active directory in my network. So I decided
to create a new domain with a new active directory.

The problem is that I have 1 server configured as a DC for the old domain.
As I run DCPromo and try to remove AC there's a message indicating that
"this server is not the last DC in the Domain".

Is there any way to remove AC or remove the Domain Controller attribute from
a server if there's no access to the old domain? I configured this server
with a lot other software so reinstalling is a choice i'm keeping for last.

Any key in the registry? Any KB available?

TIA

With SP4 (maybe SP3) you can run DCPromo /Forceremoval

You can use the /forceremoval switch with dcpromo to remove AD in this
scenario.
