Microsoft Server 2012 R2 RDS 5 Device CAL 

Need help determining your licensing scenario? Take a look at the guide below:

Windows Server Licensing Guide


Includes five (5) Microsoft Remote Desktop Device CALs. Allows access into your Terminal Server for 5 concurrent devices. No users have to be licensed, rather the individual workstations connecting into the server.


Licensing Requirements

This license will work on Windows Server Standard and Datacenter 2012 and 2012 R2. Wither you are currently in the grace period or surpassed it, we include instructions on registering your CALs and removing the grace period key.

You'll need to purchase RDS Client Access Licenses (CALs) and install them on the RD Licensing server. These RDS CALs are tied to the server, but RDS lets you move them to new hardware if needed. Remember that RDS supports both per-user and per-device licensing. The model you choose should depend on whether you have more users or computers. If you have more users than devices, it will be more cost effective to purchase device CALs. Adversely, if you have more devices than users (most common), you will want to purchase user CALs which can be found HERE.


Terminal Server Roles

Install the RD Licensing role service just as you did the RD Session Host role service (we provide easy step-by-step instructions in the licensing email).

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. Be sure to model on the same machine type (physical or virtual) you intend to use. 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.
