you need to set sharing on virtually every folder you intend to use. Then make sure you have something [any file] in the sharing folder. You must also ensure that each pc/laptop is on the same workgroup. The biggest problem normally is the firewall on each pc. I normally set the IP address of each other pc as trusted in the firewall on the other pc. Once done you should be able to see the other pc/laptop by double clicking network places - workgroup - mshome.
