Syntax
Start-DnsServerScavenging
[-ComputerName <String>]
[-Force]
[-CimSession <CimSession[]>]
[-ThrottleLimit <Int32>]
[-AsJob]
[-WhatIf]
[-Confirm]
[<CommonParameters>] Description
The Start-DnsServerScavenging cmdlet notifies a Domain Name System (DNS) server to attempt a search for stale resource records. The successful completion of this command triggers an immediate start to a scavenge.
Although this command to start a scavenge appears to complete successfully, the scavenge does not start unless the following preconditions are met:
- Scavenging is enabled for both the server and the zone.
- The zone is started.
- The resource records have a time stamp.
You can use the Verbose parameter to display all the records that the command deletes. You can press Ctrl + C to end a scavenge that is running on a DNS server. If the DNS server cannot run scavenging, the cmdlet displays the reasons why the scavenge did not start.
Examples
Example 1: Start a DNS server scavenge
