Remove AD off a deleted DC

[Hywel]

Hi,

We have a DC which is at a remote office this location wasn't used for a
couple of years and wasn't able to sync. This DC has now disapeared (not
quite sure how) from sites and services at the head office. We need to get
this DC back up and running, but i cannot demote it using DCPROMO i get the
error:-

The operation failed because:
The Directory Service failed to replicate off changes made locally.
"The DSA object could not be found."

What is the next best course of action, remove AD via another method or try
and manually install the NTDS settings.

Thanks in advance

Hywel

You can use the /forceremoval switch with dcpromo in this case. This will
rip AD from the DC and you can then do the metadata cleanup process from the
216498 article provided by Lanwench. Once these are both done you can
re-promote the server.
