users access it? I have set up a home network in XP...when I right-click a folder on my computer and select properties and then select the sharing tab, if I select the "share this folder on the network" tab, how can I be sure that people on the internet cannot access it? I don't think I get a prompt to choose just to let people on my home network access the folder...how can I limit it just to my home network, is that the default? Am I ever at risk of people on the internet being able to access it? Thanks!
