DNS_ERROR_SOA_DELETE_INVALID

The zone SOA cannot be deleted as an ordinary record

The SOA RR is structural zone data. RFC 1035 defines the SOA fields used for zone authority and refresh timing, and zone-transfer protocols use SOA information to represent the authoritative zone version and boundaries of a full transfer. Windows DNS therefore does not treat deletion of the zone SOA like deletion of an arbitrary A, TXT, or SRV RRset.

If the goal is to change the primary server name, responsible mailbox, serial-related data, or timers, modify the zone or SOA properties through the supported management interface. If the goal is to remove the zone, delete the zone as a zone operation. Attempting a raw record delete against the apex SOA is the wrong lifecycle operation and can be rejected before ordinary record processing.

What to inspect

Confirm the owner name is the zone apex and the RR type is SOA.
Use zone property management to change SOA fields instead of deleting the RRset.
Use an explicit zone deletion workflow when the entire authority is being retired.
