This is to allow an organization to configure and test its RDS environment to ensure that everything works as expected before purchasing and installing CALs. The Remote Desktop Services (RDS) role in Windows server requires appropriate client access licenses (CALs) to be installed in order to function properly, but there is a 120-day licensing grace period which begins when the role is installed. During this grace period, RDS will function without any CALs having been installed.
