If the domain is a Child domain and if you wish to delete Child domain entries / Trust from the root forest.

We received an error while decommissioning the child domain

The Operation Failed because :

Active Directory Domain Services Could not be removed on this Active Directory Domain Controller because this is the last AD DC in the domain, and the domain has a child directory partition

DC=DomainDnsZones,DC=domain,DC=com.

Use ntdsutil to Delete the Child domain

Open the CMD prompt
NTDSUtil
Domain Management (In 2008 it changes to “partition management”)
Connections => connect to server DC01
Quit
List <— to see zones
Delete NC DC=DomainDNSZones,DC=Domain DC=Com (This Deletes the CrossRef Object)
Force replication, validate that the partition is gone.
Restart DNS, the service will re-add the partition.

Now Demote the Last domain in the Child domain. it should allow you to demote without any issues.
