This question already has an answer here:
I have a windows server 2012 in the office.
I want 5 users to be able to access it and work on it at the same time.
They are each connecting from their computers, in the same network, via Remote Desktop (Some windows, some mac).
Right now when we try to do it, the active user gets kicked out by the incoming user.
do I need to purchase CAL? which are the correct CAL to purchase?
