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.

Refresh

Specifies the minimum time that 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 renewal interval. For DHCP servers running Windows Server 2008, the default lease renew interval is four days.
