Is it possible to add and configure RD Gateway role to a Server 2012 instance without setting up AD?
I've already tried it and it turns out that I can setup everything (even licensing) except the RD Session Host, which in my experience required AD.
The scenario is quite simple: I have limited number of PCs in the local network and I need to be able to access them via RD. I do not need RemoteApp or any other functionalities.
