[Installation] Domain Controller
I do not see a reason why installing is not possible on a domain controller. I have a single Windows Server 2016 running that has the essentials role enabled and it would be nice to manage this one through the new web interface.
it's needed if you have only one server
It's a huge security risk to install applications, especially potentially internet available web applications, on a domain controller. That being said, SO MANY BUSINESSES only have a single server for their organization - between hardware and licensing and maintenance overhead it's just not practical to have more than a single server.
I was an avid user of Windows Home Server, when it was deprecated, Windows Server Essentials was used to replace it. Now that I'm using Windows Server Essentials 2016, I too, would like to install this on my server to then manage my clients. But was frustrated to see that it cannot be installed on a domain controller. While I understand some of the ramifications, there are some who want to learn and use this in their very small environment. Installing on another machine isn't really an option as I would like the gateway option so I can also evaluate connecting to Azure and managing IaaS VMs. Thank you!

I'm blocked from upgrading Honolulu because of this.
One issue I understand there is that, the local user and group feature is now the AD users and groups, which is not honolulu can manage now.
