Are you using the AD Connector? If not, then resolv.conf should not look like that. It should look like mine:

There should be another file, /etc/resolv-peerdns.conf, which looks like:
I don't know where the search domain comes from in this case as it is upstream of me. It is important to have:as your first resolver or local DNS resolution does not work for the server as you see.

There is an update for the AD connector environment which is going to come out fairly soon, I think, which will bring it into line with the above set up. In the meanwhile I suggest you add the loopback IP as your first resolver.

[edit]
I didn't mean nick.conf but you can add the file and it will do as I intended. It is my own file. Otherwise you can create any other file you want in that folder or edit /etc/dnsmasq.conf and change that, but to be honest it is probably not your issue so not worth the effort.
