Dynamic DNS updates fail from one server with secure update errors

Scenario

A member server should register its records automatically, but secure update errors prevent changes.

Recommended Resolution Path

1. Confirm the server account can authenticate and that the zone permits secure updates.
2. Check whether stale records are owned by another security principal.
3. Delete the stale record carefully if ownership prevents proper refresh.
4. Document the update credentials model so DHCP and servers do not fight over records.

Technician Notes

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