Topic "server 2012 R2 hyper-v VM console" a message from macky4546

I have hyper-v host with server 2008, 2008 R2, 2012 and 2012 R2.
The RDM works great when trying to view the hyper-v console on all the machines except the 2012 R2.

When i try to open the session on the 2012 R2 box nothing shows and i dont see any VM's

how to do i get this resolved?
