Hi all, I have a doubt on share folder password... I have a home network of 2 machine, 1 laptop(A) n 1 desktop(B)... I share folder vice versa... However, everytime whn A accessing B share folder, it only sometimes prompt for B local password... Is it possible to prompt for password always? Beacause im afraid others might hack into my wireless network and access my file... Thanks in advance
