To remove a DNS server from the network, perform the following procedures to make changes in zones where the server is configured as an authoritative server for the zone:
Use the Delete a resource record procedure to remove the address (A) resource record for the server.
Use the Modify an existing resource record procedure to update the name server (NS) records, in zones where the server is configured as authoritative, to no longer include the server by name (as it appeared in the A record that was deleted in procedure 1).
If the server is the primary server for a standard zone, use the Modify the SOA record for a zone procedure to revise the owner field of the start of authority (SOA) resource record for the zone to point to the new primary DNS server for the zone. (If the zone is a directory-integrated zone, this procedure is not necessary.)
Use the Verify a zone delegation procedure to check the parent zone to ensure that any records (NS or A resource records) that are used for delegation to the zone are revised and that they no longer point to the removed server.
