Setting up access restrictions for computers on same network

[taobert]

Ok in nutshell.. 4 computers on same workgroup, all running windows 7. A neighbor is connected on network as well, but I do not want the neighbor to see any of the files on the other 4 computers without preventing them from internet access. In addition, the 4 computers are part of a business and require file and print sharing. I'm a little confused as well- I thought that being on a separate workgroup would prevent neighbor from seeing the files, but for whatever reason they are showing up in network. What are some solutions? Many Thanks!

Make it where you have to use a user name and password to get into the shared folders. if you dont know how to do this, go to Control Panel\All Control Panel Items\HomeGroup, click Advanced sharing settings and turn off Public Folder Sharing and turn on Password Protected Sharing. do this on all 4 of your computers that are part of the business.
