A client currently has SERVER 2003 running Terminal Services with SBS 2011 as the domain controller. I want to get him off SERVER 2003 for everything except their accounting system due to the OS age. The accounting system will not run on a newer OS and would require 10's of thousands of $$ to upgrade - not in the cards now.
What do I need in the way of CALs for SERVER 2012R2 and RDS? I know I need RDS CALs. Do I also need SERVER CALs to simply connect to the server to then run RDS? I have a vague recollection of needing both types of CALs.
