AD DNS zone missing new SRV records after DC promotion

Minimal guidance for messy support realities.

Scenario

A domain controller promotion completes, but expected service locator records are absent from the integrated DNS zone.

Recommended Resolution Path

  1. Check Netlogon registration, zone replication, and DNS server health on the new DC.
  2. Force record registration only after confirming the zone is writable and healthy.
  3. Compare the new controller against an existing healthy DC for missing records.
  4. Do not let clients prefer the server until service records are correct.

Technician Notes

Capture the exact scope of impact, confirm which dependency failed first, and document whether the issue reflects broader domain or server drift.
