I have a dedicated Windows Server 2016 server hosted by a company. Right now, we use Remote Desktop Connection (RDC) to allow up to two simultaneous users the ability to log onto the server remotely.
We now need to allow a few more users onto the server simultaneously. I understand that we need to use Remote Desktop Services (RDS) and buy a CAL for each potential user. The hosting company says that they can set this up and that we'll pay a monthly fee per CAL to them.
My question: if we go this route, can we still use RDC for two users, and RDS for the others? That is, if we need to allow up to 5 simultaneous users, do we need to buy 5 CALs or can we buy 3 CALs and then have two additional users access the site via RDC?
