I have a virtual Windows 2012 Server instance that is a stand-alone system. I would like to make it possible for 3 people to remotely connect to the server at the same time. What is the simplest way to allow for this? (I will purchase the CALs as necessary.)
I have tried just installing the session host role but that role doesn't stick (after restarting) and it's not clear whether I need the other related services too.
