All the servers on my RDS farm are joined to a domain, the licensing server shows no errors on Licensing Diagnostics, but this message is being displayed on all sessions:
"There is a problem with your license for Remote Desktop and the session will end in 60 minutes."
RDS Licensing Server shows that the CALs were assigned to the user, but it keeps showing the error on the sessions, which are disconnected after 60 minutes.
The licensing mode is Per User. I've already set up on the Server Manager, enforced on GPO settings, but still shows the same error.
