Demoting old remnants of Domain Controller from Active Directory
When I perform the repadmin /replsum command, I can see there is an error pointing to the oldDC12.domain.com ?
And also when I do netdom query dc command the old DC is still there.
How can I safely decommission it without causing any issue with Exchange and AD replication ?
Senior Systems Engineer
Pretty much the Domain controller has been turned off or not properly decommissioned. So how do I clean it up safely ?
Senior Systems Engineer
So I assume that the normal AD replication and Exchange is not impacted when I remove this old DC remnants.
Senior Systems Engineer
which path should I choose ?
To clean up server metadata by using Active Directory Users and Computersor
To clean up server metadata by using Active Directory Sites and Services
or do I follow both steps ?

You may also need to delete DNS records referring to the server after that. In my experience, the metadata cleanup sometimes removes these records but not always, and I'm not sure why it's inconsistent.
