  • Microsoft Windows NT Server version 4.0

SYMPTOMS

In DNS Manager, you may notice that A records randomly appear and disappear without you entering or deleting them.

CAUSE

This issue will occur if your DNS zone is configured to query WINS.

RESOLUTION

These records are not a problem, but if you wish to alter the amount of time they appear in DNS Manager you need to edit the Cache Timeout Value using the following steps:

  1. From DNS Manager, right-click the zone where the entries are appearing.

  2. Click Properties, click WINS Lookup, and then click Advanced.

  3. Change the Cache Timeout Value to the desired setting.

  4. Click OK, then click OK again.

MORE INFORMATION

When DNS resolves a query through WINS, DNS will cache the name in memory for the amount of time specified in the 'Cache Timeout Value' field under the Advanced WINS Lookup configuration of the zone properties. The records are visible from DNS Manager only, and they do not get added to the actual zone file. Only successful name queries are placed into cache.
