DNS_ERROR_ZONE_HAS_NO_NS_RECORDS

DNS_ERROR_ZONE_HAS_NO_NS_RECORDS means the zone is missing Name Server (NS) records. NS records identify the servers authoritative for a zone and are critical for correct referrals and zone administration.

What to check

Inspect the zone root for NS records and make sure their host names resolve to valid address records.
Verify that the zone delegation in the parent is consistent with the zone’s own NS set.
Correct stale or missing NS records deliberately, especially after DNS-server migration or rename operations.

Get-DnsServerResourceRecord -ZoneName "contoso.com" -RRType NS
