Sorry if about the tags, it would not let me ask the question without adding them.

I wanted to create a .bat file that I can run on our workstations.

It needs to ask for elevation since the commands I am executing need admin rights.

I want to check the current DNS settings with ipconfig /all then be able to select between these two commands:

netsh interface ipv4 add dns "Ethernet" 10.100.0.11 index=2

netsh interface ipv4 add dns "Ethernet 2" 10.100.0.11 index=2

then run ipconfig /all again to verify the change.

    Hi, Cyrus Hosmer

    This is Chaboon.

    Wouldn't it be better to try using powershell instead of a bat file?

    And you use Startup Script via Group Policy, the command execute Administrative privileges.

    See below the article (see Example1)
    https://learn.microsoft.com/en-us/powershell/module/dnsclient/set-dnsclientserveraddress?view=windowsserver2022-ps

    You can use the InterfaceAlias option instead of the InterfaceIndex option.
    The InterfaceAlias ​​option allows you to specify a network friendly name (for example, Ethernet 1) instead of an index number.
