Get Conditional Forwarders with IP addresses - Add or Remove Multiple Conditional Forwarders

The below PS script exports the conditional forwarders and their master server ip addresses

gwmi -Namespace root\MicrosoftDNS -Class MicrosoftDNS_Zone -Filter "ZoneType = 4" |
Select -Property @{n='Name';e={$_.ContainerName}}, @{n='DsIntegrated';e={$_.DsIntegrated}}, @{n='MasterServers';e={([string]::Join(',', $_.MasterServers))}}, @{n='AllowUpdate';e={$_.AllowUpdate}} | Export-Csv "condForwarders.csv"

 

The below command reads a txt file for the conditional forwarder names and for each name it creates a AD integrated conditional forwarder. The master server ip can be read from txt or hardcoded lke I do in this example.

Import-Csv "c:\arecords.txt" |
foreach{Add-DnsServerConditionalForwarderZone -Name $_.name -ReplicationScope "Forest" -MasterServers 172.10.10.200}

 

arecords.txt content can be something like this:

name

test1.com

test2.com

test3.com

test1.net

test1.biz

############

You can use the below command to remove the existing Conditional Forwarders by using the csv content

Import-Csv "c:\arecords.txt" | 
foreach{ Remove-DnsServerZone -Name $_.name -Force -Confirm:$false }
