When adding a host record to Microsoft Windows NT 4.0 Domain Name Service (DNS) Server, if you check "Create Associated PTR Record" and click Add, a dialog box appears with the message:
   Warning: Creation of the associated pointer record failed, probably
   because the referenced Reverse-Lookup zone could not be found.

NOTE: This error does not occur if the Reverse-Lookup zone already exists.


This record is caused by a missing or incorrectly defined reverse lookup zone.


For instructions on creating a DNS Reverse-lookup zone see the entry "Creating a Primary Zone in the domain" in the How To section of the online help for Microsoft Windows NT DNS Manager. The following list identifies some common problems and examples of invalid reverse-lookup zones and steps to correct them.
  • A reverse-lookup is not entered at all.
  • A zone name entered without a period between the address and the section of the name, or with a period instead of a hyphen between 'in' and 'addr':
  • The network number is not correctly entered, such as (assuming an IP address of 10.10.6.x):
  • A domain name is entered instead of
  • An incorrectly subnetted reverse-lookup zone is entered.
