Description
Establishes the maximum time that an SOA (Start of Authority) record can remain in the Domain Name System (DNS) cache.
This entry establishes a ceiling for Time-to-Live (TTL) values of SOA records. By default, the TTL value in the DNS answer determines how long records are saved in the DNS cache. However, if the TTL value in the DNS answer exceeds the value of this entry, it is ignored, and the DNS client sets the TTL 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 establishes a customized maximum TTL for SOA records. The maximum TTL for all other DNS records is determined by the value of the MaxCacheEntryTtlLimit entry.
