Adding name servers to multiple DNS zones with PowerShell

Voiced by Amazon Polly

I ran into a little problem today where I needed to add multiple DNS servers as name servers to multiple DNS zones all in one go. So this is essentially adding NS resource records to a zone, but doing it for multiple zones all at once. Yes I could have done them manually, but that’s boring and time consuming. So, here’s a quick one-liner that does the trick, obviously substitute in your DNS server and name server FQDNs in the correct places. If it fails for any reason it will continue on, but report the zone it failed on.

Get-DnsServerZone -ComputerName | where {$_.zonetype -eq "primary" -or $_.zonetype -eq "secondary"} | ForEach-Object {try {Add-DnsServerResourceRecord -ZoneName $_.zonename -ns -ComputerName -name $_.zonename -NameServer -ea:stop} catch {"$_"}}

Hope someone finds that useful.

    Hi Mark

    there is nothing on the whole internet that i could find to help me out including Microsoft articles. Microsoft dont even provide an example command about Name Server.
    thank you so much for the script and it ran successfully. i had to add new name servers to around 50 dns zones and i did not want to do it manually.
    but i when i did the opposite to remove old NS and change the Cmdlet to Remove -DnsServerResourceRecord it gave me error saying “A parameter cannot be found that matches parameter name ‘ns’.”
    i dont understand ns parameter works when adding name server but does not working when removing.
    I have lots of old Name servers and i was thinking that could use the script for same purpose

    1. Hi Muhammad,

      It seems for a removal you have to specify the NS value under the parameter “RRType”

      So for adding a record NS is a parameter as in the example in the post, but for removal it’d be like this:

      Remove-DnsServerResourceRecord -RRType ‘Ns’

      I have no idea why they’re done differently, there might not even be a sensible reason, but as a reference the Microsoft documentation for both commands is here:
