I am getting these errors:

SERVER  Error   DNS: DNS servers on vEthernet (Intel(R) 82567V-2 Gigabit Network Connection - Virtual Switch) should include the loopback address, but not as the first entry.  Configuration

SERVER  Error   DNS: The list of forwarding servers must not contain the loopback address 127.0.0.0.    Configuration

My configuration is as follows:

Ethernet adapter vEthernet (Intel(R) 82567V-2 Gigabit Network Connection - Virtual Switch):

   Connection-specific DNS Suffix  . : 
   Description . . . . . . . . . . . : Hyper-V Virtual Ethernet Adapter #2

                                       192.168.2.254

   NetBIOS over Tcpip. . . . . . . . : Enabled

What do I need to set the DNS servers to?

  • If you're specifying `::1` as a v6 DNS server, you'll need to at least specify one other non-localhost v6 DNS server. – EEAA Jul 21 '14 at 18:04
  • so IPv6 could be what is triggering the errors? I just need to add more IPv6 IPs. – Jason Jul 21 '14 at 18:05
  • To recommend the best practice for configuring your server requires a bit more info - does this DC also run DNS (it likely does unless you've consciously decided to separate them out)? Do you have any other DCs/DNS servers in your environment, or is this the only one? – dbr Jul 21 '14 at 18:50

Remove the ::1 and 8.8.8.8 from your network card config. Instead go into the actual DNS server and setup a forwarding address to 8.8.8.8

I've seen issues with things not resolving properly for local DNS zones.

Also where ever you used 127.0.0.0 change that to 127.0.0.1

  • In this case, I think replacing 127.0.0.0 with 127.0.0.1 would be wrong. It needs to be removed from the list of forwarders completely – dbr Jul 21 '14 at 19:02
  • @Newt Yes I agree, but if he setup his DNS server to listen on 127.0.0.0 then that would need to be changed to 127.0.0.1 – George Jul 21 '14 at 19:16
