How do I get rid of the many DNS entries on our office server

skenny10 asked
When I run the IPconfig /all command on our office 2012 r2 server, I am receiving a large number of DNS servers in the list. Instead of the responce just listing the IP address of the server itself ( and and then letting the forwarder on this server take over, I also see the following DNS servers in the list.

How do I remove all of these entries?

Thanks for your assistance.

Go to the properties of your NIC > then the TCP/IP v4 properties > advanced > DNS tab.  Remove all DNS servers except your internal ones.  I can't imagine why someone would add all of these.

It's fine to have them as forwarders in the DNS config, but they should never be used on the NIC configuration of a domain machine.
