Hi,
To remove a domain from a forest, we need to demote every Domain Controller in this domain or perform
metadata cleanup using ntdsutil.exe tool.
We can run Dcpromo.exe to demote a DC, please remember to select
This server is the last domain controller in the domain check
box when you are demoting the last DC in
the domain.
Please make sure that DCs in this domain don’t holder any forest-wide FSMO roles.
If all domain controllers have been taken offline without demotion process, we can
perform metadata cleanup to remove this domain.
You can use ntdsutil.exe tool to connect to the
Domain Naming Master role holder, then remove the specific domain from the forest.
