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.
