DNS Server - PowerShell - Domain Controller Removal from Name Servers

[Luk3r]

All,
As I head through a major refresh I realized it was way too cumbersome to manually remove decommissioned domain controllers from the 'Name Servers' tab inside of DNS forward and reverse lookup zones. I came up with the below script to automate the removal of these records. I hope this helps others in the future.

All you need to do is modify the FQDN (Fully Qualified Domain Name) on Line 2.

        #FQDN of the domain controller that has been decommissioned or is offline
        $oldDMCName = "DMC1.domain.org"
 
        #Get the PDC Emulator
        $PDCe = Get-ADDomainController -Discover -Service PrimaryDC
 
        #Get all DNS zones on the PDCe
        $DNSZones = Get-DnsServerZone -ComputerName $PDCe
 
        #Iterate DNS zones and remove the stale domain controller record where applicable
        ForEach($zone in $DNSZones)
          {
            $zone = $zone.zoneName
            $getZoneInfo2 = (Get-DnsServerResourceRecord -ZoneName $zone -Name "@" -RRType NS -ComputerName $PDCe).recorddata.nameserver
            If($getZoneInfo -like "*$oldDMCName*")
              {
                Try
                  {
                    Remove-DNSServerResourceRecord -ZoneName $zone –Name “@” –RRType NS –RecordData $oldDMCName -ComputerName $PDCe -Force
                  }
                Catch
                  {
                    Write-Output "Error removing $oldDMCName from $zone"
                  }
              }
            Else
              {
                Write-Output "$oldDMCName does not exist in zone $zone"
              }
          }
