I just installed my first 2012 R2 server. It has a USB license dongle attached to it.
When I log in locally to the server, the license manager of the business software installed on the server can see the license dongle and the licenses on it.
However, when I connect to the server via Remote Desktop and open the license manager, the license manager can't see the dongle or the licenses on it.
I have tried remote desktop from Win7 SP1 and Win8.1, and they both act the same.
I had this business software installed on a Win2003 server, and didn't have this problem.
I'm guessing there is a setting in the 2012 R2 equivalent of 2008 R2's Remote Desktop Session Host Configuration, but I can't find it.
