Item Details

Scavenge stale resource records

Specifies whether stale resource records should be removed from the Domain Name System (DNS) database.

No-refresh interval

Specifies an interval of time in either days or hours. When a resource record is refreshed, it is not refreshed again until this interval of time has elapsed.


Specifies the minimum time that resource records are expected to remain in the DNS database after the no-refresh interval expires.

This interval should not be smaller than the maximum refresh period for any resource records. In most networks, this interval corresponds to the Dynamic Host Configuration Protocol (DHCP) lease renew interval. For DHCP servers running Windows Server, the default renew interval is four days.
