Configuration

Scavenging is enabled but there are no scavenging servers specified for the zone.

If record aging is enabled for the zone, there must be at least one scavenging server configured with permission to scavenge resource records in the zone.

DNS records in the zone will not be scavenged.

DNS Records in the zone will not be scavenged even through record aging is enabled. With this configuration, the zone might contain duplicate entries for some resource records.

Configure the list of DNS scavenging servers for the zone.

By default, all servers that host a DNS zone can scavenge records in the zone if scavenging is enabled. If the zone is hosted by more than one DNS server, you can limit the number of servers that are allowed to scavenge resource records. This is useful if it is preferable that scavenging only be performed by some servers loading the zone. To configure the list of scavenging servers for a zone, you must set the ZoneResetScavengeServers parameter using the dnscmd command, a command-line based tool for administering Windows DNS servers.

Membership in Administrators, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

  1. Open an elevated command prompt.

  2. Type the following command, and then press ENTER:

    Art Image dnscmd [ServerName] /zoneresetscavengeservers ZoneName [ServerIPs]

ServerName
Specifies the DNS server the administrator is planning to manage, represented by local computer syntax, IP address, FQDN, or host name. If omitted, the local server is used.

ZoneName
Identifies the zone to scavenge.

ServerIPs
Lists the IP addresses of the servers that can scavenge records in the zone. If this parameter is omitted, then all servers hosting this zone can scavenge it.

dnscmd dnssvr1.contoso.com /zoneresetscavengeservers test.contoso.com 10.0.0.1 10.0.0.2
