Windows Server 2019 TCP/IP not properly configured

If you are attempting to setup Active Directory, DNS and DHCP on Server 2019 (and probably others) and get a message that TCP/IP is not properly configured, make sure your server is plugged into a network switch such that the connection is live. I spent several minutes on this, checking adapter configuration and rebooting until I simply plugged the machine into a network switch. I was trying to configure the machine offline and didn’t have it plugged in, just had the IP, subnet mask, gateway and DNS settings input.
