Essentials 2012 static IP Changes to Obtain Automatically

I had an 2012 Essentials server setup so that DHCP was handled by the router but I had assigned a static IP address to the server.
I am in an environment that has mainly Windows 7 home systems so we were using the Server launchpad on those homes sytems to reach shared drives. We recently got a few Windows 7 pro and one Windows 10 pro systems and I joined them fully to the domain. However when I was done I got an error from the BPA scan saying that my DNS was pointed to the wrong computer. I checked network settings on the server and found that the settings were now set to 'automatically' obtain both IP and DNS addresses on the sever.  There was no static IP address now on the server. Is there any reason why after doing a join that the static IP would revert to dynamic?

No. Joining a client to a domain does not make this change on the server and, in fact, the computer accounts that are created during the join process wouldn't even have the necessary permissions. This happened some other way.

That is strange. When I do an ipconfig I am getting the IP address that I originally assigned. This is a small network (8 computers) and I assigned the IP address to the server and let DHCP be handled by router as I was told Essentials will work this way. Essentials is handling DNS but not DHCP. I'm thinking I will just change it to use the same IP in network properties and see what happens. Nothing seems to be broken, everything is working, the only issue is the BPA hits me with a warning to set the DNS server to this server, but as it's not got the IP address I can't do that unless I reassign the address.

I set the static IP by going to network properties->ip4->properties, and then said Use this IP which was the IP that I got from IPCONFIG /all. I installed DNS server role but not the DHCP role. Is there some other step?

Nope. That's the process for setting a static address.
