Hi there,

DNS is a Server Role, Its as simple as adding or removing the role?

What exactly are you trying to achieve?

Hi, what exactly do you mean with add new DNS servers to server core? Add new records, forwarders, or install the actual DNS server role on a core?

To remote manage a DNS server on a core you need to install the DNS Server Tools on a 2012 server that has a GUI (usually this is a management server specific for used for managing the environment) through the "Add Roles and Features Wizard".

On a Windows 8 client you could install the RSAT, Remote Server Administration Tools, to get the DNS management tools.

Thanks for getting back. This server needs the DNS servers it currently uses to be changed to new servers. It does not have a DNS role on it

Ok, that is something different, confusing title :)

First run this in Powershell and remember/write down the IfIndex number you see in the result:

Get-NetIPInterface

Open in new window


When you have the IfIndex number (in our example it's number 11) use following commands in powershell:

First remove the currently configured addresses:

Set-DNSClientServerAddress -interfaceindex 11 -ResetServerAddress

Open in new window


 Now set the new DNS addresses.

Set-DNSClientServerAddress –InterfaceIndex 11 -ServerAddresses 192.168.0.1,192.168.0.2

Open in new window

Oh! You want to change what DNS its looking at, not make it a DNS server.

Please have a look at this link which helps explain how to do this.
