Which service is responsible for registering a domain controller's SRV records in DNS during startup?

Active Directory Domain Services

Kerberos Key Distribution Center

A Samba AD environment uses an external BIND DNS server for the domain zone. The zone is configured to allow only secure dynamic updates. A new Samba DC was promoted, but its SRV records are not appearing in DNS. The DC's Netlogon service is running. What is the most likely cause?

The Samba DC is configured to use its internal DNS server instead of the external one.

The Netlogon service only registers A records, not SRV records, so the absence of SRV records is normal.

The Samba DC's Kerberos credentials are not authorized to update the DNS zone, so the secure update is rejected.

The external DNS server does not support SRV records, so they cannot be stored.

Why does Active Directory require DNS to support dynamic updates?

To allow DNS administrators to manually add records for all domain controllers

To provide secure communication between DNS servers and clients

To allow clients to register their IP addresses automatically

To enable domain controllers to register and update their SRV and A records automatically
