hi my main computer is a mac, but i am part of a network with several PCs. one of these pcs is my laptop and i have set up various shares using the 'SharePoints' utility so that this laptop can access folders and volumes on the Mac. what i would now like to do is to restrict access to some of the other PCs. to be specific i would like some of the PCs to be able to access folders as read-only and others to be blocked from accessing any of my shares (except the 'public' folder). i am not sure if i can restrict shares to certain PCs using SharePoints, or whether i need to use another method. i can't find a help section for SharePoints and would be grateful for some help thanks nick.
