Establishes the maximum time that a DNS record, other than an SOA record, can remain in the DNS cache.
This entry establishes a ceiling for time-to-live (TTL) values of non-SOA records. By default, the TTL value in the DNS answer record determines how long records are saved in the DNS cache. However, if a TTL value in a DNS answer record exceeds the value of this entry, it is ignored, and the DNS client sets the TTL to the value of this entry.
To make changes to this entry effective, restart the DNS client service or restart Windows 2000.
This entry does not apply to SOA records. The maximum TTL for SOA records is determined by the value of MaxSOACacheEntryTtlLimit.
