Remove multiple A records from file txt with hostnames

Question

from a txt file with the hostname names I would like to delete all type a records in DNS
get-content -path c:\temp\ListHost.txt

Answer 1

Hi @joaomanoelc ,

please try this (the -force needs to be inside the {}):

Get-Content -path c:\temp\ListHost.txt | ForEach {Remove-DnsServerResourceRecord -ZoneName "contoso.com" -RRType "A" -Name "$" -Force}  

To remove the PTR record the -RRType needs to be Ptr.
Maybe this helps:

Hi @joaomanoelc ,

maybe this helps to get started (not tested by myself!):

Get-Content -path c:\temp\ListHost.txt | ForEach {Remove-DnsServerResourceRecord -ZoneName "contoso.com" -RRType "A" -Name "$_"}  

You have to modify the ZoneName for you needs.
