I am purchasing a new Database Server for a small office. I am planning to use windows 2008 Enterprise R2 as a host and run at least 2 Hyper-V's (one containing the Database). I have users who will need to Remote Desktop into the Database Server from outside the network. I have 25 users but only 5 will need to RDP into the Server at any time (concurrent). What type of CAL license will be required?
Do I apply it per user or per device?
