Hi,
My customer is using Dell WYSE ThinOS(Thin Client with native OS) to remotely connect through VMWare Horizon Blast protocolto a Virtual Machine that is running an application on Windows Server 2016. Generally we would use RDS CAL if the Remote Thin Client is also a Windows Desktop that uses Remote Desktop Protocol. However here it is Blast protocol. is a RDS CAL needed in this instance just because the guest machine is a Windows Server Operating system?
