I haven't been keeping up with Windows Admin Center for awhile. Was that an option to manage Hyper-V?
It will be, but I'm not sure that it is yet. We've tried and not been able to get it working even internally anywhere, let alone externally. Once they figure out stability and authentication, I assume that it will be great for that. Being that this is 2016, it's going to suck hard. And if there is a Hyper-V issue, WAC would be down which is a problem in a small environment like this.
