Q. Can I use my Windows Server 2008 TS CALs to access RDS on a server running Windows Server 2008 R2? A. Yes, Windows Server 2008 TS CALs are functionally equivalent to RDS CALs, and can be used for connecting to Windows Server 2008 R2 RD Session Hosts and RD Virtualization Hosts. -----Original Message----- From: Matthew W.
