just deployed windows 2012 r2 essentials server with 10 user Remote Desktop CALs setup but when I try to get more than two users logged in I get an error about disconnecting a current logged on user before the new RDP session can be made
Have missed a configuration step?
is this a limitation with r2 essentials? and if so; can I upgrade the server in place or do I need to reconfigure completely from scratch?
all help is greatly appreciated
