Server 2008r2 DNS server does not display TTL for NS records


when editing zone's ns records ttl fields shown empty.

examining zone dns file shows ns records may have value not getting displayed.

i have noticed when enter ttl ttl control on edit window ns record updates zone file sometimes which makes me think broken.

can modify default ttl on soa affect ttl records have not been explicitly set or new records. problem trying solve why ttl ns record not shown in edit ns record window when record has ttl not equal default minimum ttl of soa. other record types not affected in way. control there appears faulty

why ttl ns records not populated in control shown in screen shot? not populate:

  • if ttl different soa default minimum ttl.
  • if explicitly set ttl different soa default.
  • at all.
