Hi,
Remote Desktop Services is currently not supported in the Q&A forums, the supported products are listed over here https://video2.skills-academy.com/en-us/answers/products (more to be added later on).
You can ask the experts in the dedicated Remote Desktop Services forum over here:
https://social.technet.microsoft.com/Forums/en-US/home?forum=winserverTS
Also note that licensing questions are best directed to a trained Microsoft licensing specialist.
(Please don't forget to accept helpful replies as answer)
Best regards,
Leon
