Metadata Cleanup of a Domain controller - SERVER 2012R2

Question

Hi,

For Server 2012R2: After a DC is dead, we have to use the following to cleanup metadata:

https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/ad-ds-metadata-cleanup

As far I understand, this will not remove the DNS records of this dead domain controller. We have to remove the DNS records manually.

Do we also have to delete DNS records in root domain (example.com) of DNS? Or do we only delete the DNS records from _msdcs.root domain ( _msdcs.example.com)? As far as I understand, there are always two zones for domain example.com:
example.com and _msdcs.example.com

Hi,

As far I understand, this will not remove the DNS records of this dead domain controller. We have to remove the DNS records manually.

Some DNS records can't be deleted automatically, you have to check and cleanup DNS records manually (NS,SRV,A,AAAA).

Do we also have to delete DNS records in root domain (example.com) of DNS? Or do we only delete the DNS records from _msdcs.root domain ( _msdcs.example.com)? As far as I understand, there are always two zones for domain example.com:
example.com and _msdcs.example.com

Yes you should delete all DNS records of deleted domain controller in the different domains example.com and _msdcs.example.com.
