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?
