SYMPTOMS

Your network, which is using a Microsoft Windows NT Domain Name Service (DNS) server, may experience one or more of the following problems:

  • DNS Manager on your DNS server may display some of the zone objects with a red X, indicating that they are disabled.

    -or-
  • DNS clients on the network may be unable to resolve reverse name lookups successfully.

CAUSE

Your DNS server has its reverse zone, in-addr.arpa, configured as a subdomain of the root zone (.).

RESOLUTION

To resolve these issues, reconfigure your DNS server so that the reverse zone, in-addr.arpa, is a separate zone and not a subdomain of the root zone. Then add your PTR records or delegations within the in-addr.arpa zone.
