DNS_ERROR_RCODE_NOTAUTH
DNS_ERROR_RCODE_NOTAUTH means the contacted server is not authoritative for the zone named by the request. For updates and transfers, this commonly means that the request was sent to a secondary, a resolver, or the wrong primary server.
What to check
- Confirm the zone origin and identify the authoritative primary server for the intended operation.
- Check delegation and NS records when the request crosses a zone boundary.
- For managed updates, direct the operation to the proper writable primary or AD-integrated DNS server.
