No Remote Desktop License Servers Available

No Remote Desktop License Servers Available 2008 R2

This problem occurs if a RDP license server is unavailable to provide a license to start a remote session. It can be caused by several scenarios, even though a Remote Desktop Session Host role was set up on the machine:

• There was never a Remote Desktop licensing role in the environment, and the grace period (180 days) is over.
• A Remote Desktop license in the environment doesn't have Client Access Licenses (CALs) injected to set up the connection.
• A Remote Desktop license was installed in the environment. There are available CALs, but they weren't configured properly.
• A Remote Desktop license has CALs, and it was activated. However, some other issues on the Remote Desktop license server prevent it from providing licenses in the environment.

Solution:

• Open the regedit (Registry editor) and go to the below location and delete the GracePeriod folder and restart the server. It will reinstalled the license role for 180 days

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod

Permission issue deleting GracePeriod:

• Our user has no privileges to delete the GracePeriod folder so we have to make the user to owner grant all permissions
