RDC for MAC cannot connect to RDS 2012 server with error message "You were disconnected from the Windows-based computer because of problems during the licensing protocol".
It works perfectly when connecting PC's.
I've temporarly solved it by installing 3d party RDP software on the Mac.I've tried from several Mac's (from latest OS to almost the lastes) and all have the same problem.
I have installed the latest RDC client 2.1.2 and also followed all suggestions here without any success (eg removing reg keys etc):
The RDS is a Server 2012 Standard joined AD on another Server 2012 Standard. License Services etc are all installed on the RDS. There are only these two serers, no more DC's or RDS's.
