Ok, so I have two computers in my house...one is mine and my sister computer, and the other one is my dad computer. so he set up a linksys router file sharing between our computer and i have got to find a way to disable it so he wont be able to explore my computer files!! of course not see my internet bookmarks and history... how can i do it? I am the administrator of my computer!! No biggie, right? Do i have to disable it from his laptop computer? I just need to not let him explore my computer from his... editing permission is useless! when he wasnt home i tried exploring my computer from his and i could change security permissions (like Modify, Read...) and just explore C and D drives, although I changed my specific folders secrutiy settings i could change them from his computer - its like he is the Workgoup network Admin he can do whatever he wants on my computer from his copmuter, i have to disable this sharing! plus - where can i learn about computer technology and all this interesting stuff? So i will be able to do things myself!
