Causa
Service Records or SRV records are registered specifically for domain controllers when a member server is promoted to a domain controller. The Netlogon service on the domain controller is responsible for registering SRV records. Because Active Directory depends on DNS, if SRV records of domain controllers are missing from the DNS Zone of the domain, critical failures of Active Directory services can occur.

The following methods can be used to re-register SRV records of a domain controller in the domain DNS zone:
• Restart the Netlogon service on domain controller.
• Run DcDiag /fix.
• Run NetDiag /fix.
• Re-register from Netlogon.dns file in \Windows or Winnt\System32\Config directory.
