Error when attempt to remove child domain form the forest via dcpromo command
The operation failed because:
Active Directory could not be removed on this domain controller because this is the last domain controller in the domain, and the domain has a child directory partition DC=DomainDNSZones, DC=child, DC=company, DC= com
The request delete operation could not be performed
The Directory Partition “DC=DomainDNSZones,DC=child,DC=company,DC=com” need to be remove from the forest before you can remove the child doamin. The Directory Partition can be deleted using the “ntdsutil” tool. ntdsutil tool is available in the support tool.

You have delete the DC=DomainDNSZones, DC=child, DC=company, DC= com directory partition. Wait for the domain controller to complete the replication before run dcpromo on the child domain again. The replication time required is depending on your domain configuration, amount of objects in your AD as well as your network speed. You can use the “replmon.exe” tool in the support tools to monitor AD replication.
