Each user and device that connects to a Remote Desktop Session host needs a client access licenses (CAL). You use RD Licensing to install, issue, and track RDS CALs.

Recover my file serial key generator. When a user or a device connects to an RD Session Host server, the RD Session Host server determines if an RDS CAL is needed. The RD Session Host server then requests an RDS CAL from the Remote Desktop license server. If an appropriate RDS CAL is available from a license server, the RDS CAL is issued to the client, and the client is able to connect to the RD Session Host server and from there to the desktop or apps they're trying to use.

Although there is a licensing grace period during which no license server is required, after the grace period ends, clients must have a valid RDS CAL issued by a license server before they can log on to an RD Session Host server.

Use the following information to learn about how client access licensing works in Remote Desktop Services and to deploy and manage your licenses:

• License your RDS deployment with client access licenses (CALs)

Understanding the RDS CAL model

There are two types of RDS CALs:

• RDS Per Device CALs
• RDS Per User CALs

The following table outlines the differences between the two types of CALs:

When you use the Per Device model, a temporary license is issued the first time a device connects to the RD Session Host. The second time that device connects, as long as the license server is activated and there are available RDS CALs, the license server issues a permanent RDS Per Device CAL.

When you use the Per User model, licensing is not enforced and each user is granted a license to connect to an RD Session Host from any number of devices. The license server issues licenses from the available RDS CAL pool or the Over-Used RDS CAL pool. It's your responsibility to ensure that all of your users have a valid license and zero Over-Used CALs—otherwise, you're in violation of the Remote Desktop Services license terms.

To ensure you are in compliance with the Remote Desktop Services license terms, track the number of RDS Per User CALs used in your organization and be sure to have a enough RDS Per User CALs installed on the license server for all of your users.

You can use the Remote Desktop Licensing Manager to track and generate reports on RDS Per User CALs.

RDS CAL version compatibility

The RDS CAL for your users or devices must be compatible with the version of Windows Server that the user or device is connecting to. You can't use RDS CALs for earlier versions to access later versions of Windows Server, but you can use later versions of RDS CALs to access earlier versions of Windows Server. For example, an RDS 2016 CAL or higher is required to connect to a Windows Server 2016 RD Session Host, while an RDS 2012 CAL or higher is required to connect to a Windows Server 2012 R2 RD Session Host.

The following table shows which RDS CAL and RD Session Host versions are compatible with each other.

You must install your RDS CAL on a compatible RD license server. Any RDS license server can host licenses from all previous versions of Remote Desktop Services and the current version of Remote Desktop Services. For example, a Windows Server 2016 RDS license server can host licenses from all previous versions of RDS, while a Windows Server 2012 R2 RDS license server can only host licenses up to Windows Server 2012 R2.

The following table shows which RDS CAL and license server versions are compatible with each other.

Tech Level: 1

When using Citrix or RDP, a user might experience the following message upon connection:

'The remote session was disconnected because there are no Terminal Service License Servers available to provide a license. Please contact your server administrator.'

This issue can be resolved typically by removing a registry key and reconnecting to the RDP or Citrix server.

  I ran into this issue because I installed the RDS role for testing on the server I was attempting to connect to and after the allotted period of time (60 or 90 days) I had to have RDS licensing so it blocked any incoming connections due to licensing. I simply removed the role, rebooted and was able to log in via RDP.
