I just installed a new Windows Server 2016 Essentials hoping to create a test environment for RemoteApp hosting. So far good, all worked great, until I started getting a "Remote Desktop licensing mode is not configured" warning message.
Running the RD Licensing diagnoser says "Number of licenses available for clients : 0"...
Well, then I started searching the web for CALs, but Microsoft's documentation is crystal clear: Essentials version contains 25 CALs and cannot be extended. Perfect in my case - but where the heck are these CALs, how can I make them available?
