Description
Establishes the maximum time that a Domain Name System (DNS) record, other than an SOA (Start of Authority) 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 value to the value of this entry.
Activation method
To make changes to this entry effective, restart the DNS client service or restart Windows 2000.

Note
This entry does not apply to SOA records. The maximum TTL for SOA records is determined by the value of the MaxSOACacheEntryTtlLimit entry.
