DNS name server IP keeps reverting back to unknown for forward lookup zone

I’ll start by saying I have not worked much with DNS and DC’s. I’m a programmer who is trying to build out an environment with a domain to simulate a production scenario.

My issue is the forward lookup zone (FLZ) I have for my domain keeps dropping the A record that gets created for the domain. When I look within the name servers for the zone the name server has the FQDN of the DC (the same machine I’m running DNS on) but it says unknown for the IP. If I resolve it by going to edit and clicking “resolve” it will populate it with the correct IP and then when I apply it it will automatically add the appropriate A record and all is good for about 15 mins or until I reload the zone. Then it disappears again and none of my other servers can access the domain appropriately.

The _msdcs FLZ has always had the appropriate ip for the nameserver and it’s been stable ever since I installed it. It’s just the FLZ. I also added a reverse lookup zone and that one has kept the IP for the name server as well without any issues.

The environment is a Server 2012 VM which I’m running using Hyper V. I have configured a private virtual switch in Hyper V for my VM’s to run on. The server I’m working on has a static IP assigned to it and I’ve disabled IPV6.

My ipconfig /all:

What could I be missing? I’ve been banging my head against this for awhile now.

Thanks for any help you can give
