How to Fix - Directory service is missing mandatory configuration

When you remove a DC gracefully from a domain, you might get "Directory service is missing mandatory configuration" error. The exact error says "The directory service is missing mandatory configuration information and is unable to determine the ownership of floating single-master operation roles."
The CN for ForestDNSZones and DomainDNSZones is (replace dc=domain,dc=com with your domain)
CN=Infrastructure,DC=DomainDnsZones,DC=domain,DC=com
CN=Infrastructure,DC=ForestDnsZones,DC=domain,DC=com
