The DNS server is listed as a scavenging server for zone, but does not host this zone.

A DNS server that is listed as a scavenging server for the zone is not responding to DNS queries for the zone.

The server cannot scavenge records in the zone.

Errors in DNS resolution might occur if no servers are available to scavenge resource records in the zone.

Remove the server from the list of scavenging servers for the zone.

To repair this condition, remove the server from the list of scavenging servers. Alternatively, you can configure the server to host the zone. By default, all servers that host an Active Directory-integrated DNS zone can scavenge records in the zone if scavenging is enabled. 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. Scavenging must be enabled on both the DNS server and the zone affected by this operation.

To display the current list of scavenging servers for the zone, use dnscmd [ServerName] /ZoneInfo ZoneName . The list of scavenging servers is displayed in the output below Scavenge Servers.

Membership in Administrators, or equivalent, is the minimum required to complete these procedures.
