First, make sure you have the appropriate licenses for your users based on the desktop and apps you plan to deploy:
Windows Server 2012 R2, 2016, 2019
RDS Client Access License (CAL) with Software Assurance
Is there any information as to how a setup for licensing WVD with a Win Serv 2016 with traditional RDS Client Access Licenses? Do we need a standard RDS Licensing server, and if so, how do we set up licensing to the RDSH server using WVD?
