I run a home based business and we have 3 computers for the business. My problem is my wife and kids also have computers and they can see the business computers and access our share folders, obviously because they are on the same network. I may be missing something simple but is there a way to kind of segregate the 3 business computers from the other home computers? I am willing to buy equipment/software....I just don't know how to go about it. Everyone is running Windows 7 Pro.
