I performed a clean install of Server 2019 Essentials and all seemed to go well.The machine has a fixed IP address of 10.1.10.10 on the network and the DNS was pointed to the router, 10.1.10.1.The installation completed without running any wizards or creating any shortcuts on the desktop.  I guess that is one of the "improvements" in 2019 Essentials.That's OK.  I wasn't a fan of the Wizards in 2016 anyway.I located Server Manager in Windows\System32.  I was able to add the A/D and DNS roles.  I logged in as NWC\Administrator, located AD Users & Computers, added an Admin
