Server not showing up in Windows 2016 Essentials Dashboard nor in Access. When I set the server up I first joined an existing domain. When I ran the initial configuration wizard if forced me to set it up as a member server. When I tried to promote to domain controller it wouldn't let me because CA was installed. So I uninstalled CA, promoted the server, then reinstalled CA according to this article: https://support.microsoft.com/en-us/help/2795825/reinstall-the-ca-role-in-windows-server-2012-essentials
I tried to run http://servername/connect
but it told me I needed to run it on a client machine. I thought about reinstalling the Windows Essential Experience but didn't want to make things worse.
