RDS and TS CAL Interoperability Matrix

RDS and TS CAL Interoperability Matrix

One question I often hear is what CAL types can be used with what OS versions of Remote Desktop Licensing Server and Remote Desktop host server.  Background information up to 2008R2 is http://technet.microsoft.com/en-us/library/hh553159(v=ws.10).aspx
                                                   
The following matrix shows which TS CAL’s and RDS CAL’s can be entered on different versions of the TS and RD Licensing Server:

Windows Server 2000
Windows Server 2003
Windows Server 2008

Notes:
 
(1) Per http://technet.microsoft.com/en-us/library/hh553159(v=ws.10).aspx to install RDS CAL’s on a Windows Server 2008 License Server, http://support.microsoft.com/kb/968074 required

(2) Despite the new name, the Windows Server 2008 TS CAL is functionally equivalent to the Windows Server 2008 R2 RDS CAL (per  http://technet.microsoft.com/en-us/library/hh553159 )

(3) Can be RDSH (Session-based) or RDVH (Virtual machine-based).

Comments
  • This may be for lack of understanding RDS, but why in the world would 2012 R2 allow you to migrate/install server 2008 RDS CALs if those CALs can't be used by end-points to connect to a 2012 RDS Session Host?

  • To the previous comment: the rdsh server can be 2008 r2 that uses a license server that is 2012 r2 with downlevel calls installed on it.

  • Bastante útil la información, gracias.
