If you’ve installed Remote Desktop Services in Windows Server 2012, then you will need to setup an RD Licensing server. If you haven’t you’ll be getting this error message:
Remote Desktop licensing mode is not configured.
Remote Desktop Services will stop working in 119 days. On the RD Connection Broker server, use Server Manager to specify the Remote Desktop licensing mode and the license server.
To fix this, log onto the RD Connection Broker server and open Server Manager. In Server Manager, click on Remote Desktop Services. Under Overview, click Tasks at the top right hand side of the Deployment Overview diagram then click Edit Deployment Properties. Use this interface to select the licensing mode and set the RD License server.
You may then get the following error whilst trying to set the deployment properties:
Could not save the settings for RD Licensing. Error: Unable to set the license settings.
If you get this error, close Server Manager, SHIFT+Right Click on the Server Manager icon, click Run as Administrator and repeat the process.
Remote Desktop Licensing Mode Is Set, But RD Hosts Aren’t Licensed
If you have set up your RD License server, but are still getting Remote Desktop licensing mode is not configured then you might need to add the RD Licensing server to be a member of the Terminal Server License Servers group in Active Directory Domain Services.
To do this, you can add the RD Licensing server to the AD group directly, but to confirm this and diagnose RD Licensing issues more thoroughly, view the Licensing Configuration in RD Licensing Manager. To view the Licensing Configuration:
- Start RD Licensing Manager on the RD Licensing Server
- Right click the RD Licensing server
- Review Configuration
If you have a yellow warning triangle with an exclamation mark in it on the RD Licensing server in RD Licensing Manager, then clicking Review Configuration should give you more details. If you haven’t added the RD Licensing Server to the Terminal Server License Servers group in AD then you will see the following error:
This license server is not a member of the Terminal Server License Servers group in Active Directory Domain Services. This license server will not be able to issue RDS Per User CALs to users in the domain, and you will not be able to track or report the usage of RDS Per User CALs on this license server.
Clicking the button Add to Group fixes this.
