The RDS Licensing server manages RDS Client Access Licenses (CAL). RDS CALs are used by users and computers to access a Remote Desktop Session Host (RDSH) server. By default, the RDS Licensing server provides two concurrent connections free of cost. If you need additional RDS CAL then you need to purchase them. To set up an RDS Licensing server in your organization's network with Windows Server 2016, you first add the Remote Desktop Services role and then add Remote Desktop Licensing role services as in Figure 5.16:
