Start-DnsServerScavenging

Start-DnsServerScavenging

Notifies a DNS server to attempt a search for stale resource records.

Syntax

Parameter Set: Start2
Start-DnsServerScavenging [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-Force] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Detailed 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.
