I am wanting some help on this one.  I have a new HP server running windows server 2012.  I have done all the configuration of the server and in the server manager DNS says there is an error that needs to be remedied.  

the error is

DNS servers on <adapter name> should include the loopback address, but not as the first entry

I have set up 127.0.0.1 as the loopbak secondary entry on the NIC,  but the error still exists.  

What am I doing wrong and how do i fix it.

server is set up as a single DC, no virtualisation, have dc, ad iis and everything else running fine.  Just have this one error.

thanks in advance

I don't think you did something wrong, might be a "false positive" so to speak ... You could try also adding the IPv6 loopback ( ::1) but I'm not sure this would do anything.

(ps: If you don't use IPv6, you could choose to disable it also of course).

That's,  tried that and then when it did not work then disabled it.

I feel the same way,  that I did nothing wrong.  DNS seems to be working,  just can't work out why.

Hmmm ... Could just be that, a "false positive"

Other things to try:

- Disable any extra NIC's in the host/system if any
- Disable IPv6 completely (registry) - (if you didn't do this yet)
- Just ignore the error/warning ;-)
