PER DEVICE– One device (used by any user) can use RD on any server.It’s on you to make sure that you’ve bought the appropriate number of CALs and that you’re obeying your licensing agreement. If you have it set to Per User, it accepts any and all connections. When you move over to user CALs, or the user mode, you need to make sure that you buy the appropriate amount of licensing. So let’s say you have executives that have both a desktop and a laptop, and even some type of a tablet, they could remote desktop on all of those devices, and even simultaneously, and you would still be within your licensing requirements. PER USER – One user (using any device) can use RDS functionality on any serverĪn RDS User CAL means that you’re licensing the user, so one user using any device, and in fact they can use multiple devices at the same time, can use Remote Desktop Services functionality on any server.Once we have installed the server we have to activate it and we need to purchase Client Access License, or CALs that match the licensing mode that we choose. Once we install RDS we must install a license server within 120 days or RD Sessions services will stop. The last piece of the puzzle is RD Licensing server. Each server already has 2 CALs for admins and that’s each and every server, but the idea is that there are just going to be used by admins to remote desktop in and go through and configure the server.
