Windows Server CAL Licensing Guide

This product includes 5 RDS Device CALs

Will work on:

• Windows Server 2008/2008 R2 Standard or Enterprise

Client Access Licenses (CALs) must be installed on the RD licensing server. Though these CALs will be tied to the server, they can be moved to new hardware if needed. RDS supports per-user and per-device licensing, and the model you choose should be determined by the number of users or computers in your network. RDS does not have concurrent-user licensing, and the licenses chosen must match the mode for which you configure the RD Session Host Server. 

Install the RD Licensing role service just as you did the RD Session Host role service. Then you must:

• Activate the RD Licensing server
• Install RDS CALs so the RD Licensing server can allocate them to users and devices
• Tell the RD Session Host server to use the RD Licensing server (you must do this even if the two role services are located on the same machine)

You can virtualize an RD Session Host server, but you'll likely see a reduction in the number of simultaneous sessions it can support.  If you do build a virtual RD Session Host server, you should probably use a server with a processor supporting second-level address translation (SLAT) to reduce the overhead of memory mapping between the physical machine and the VMs. To reduce overhead, its also advisable to use a Type 1 hypervisor like Hyper-V, not a Type 2.
