Hi ! first question : i have 2 windows xp PCs ( A and B) set up in a lan with a linksys wired router. "A" PC can see and access files from "B" PC but "B" PC can only see files from "A" PC. When i try to access files from "A" PC it tells me i need administrator privileges... (dont recall puting some password or such.) Oh by the way i tried it with all the firewalls down and up : same results Although, i can play games on the lan. second question : i want to share my dial-up internet connection. how do ? i just want it in one way that if "A" is connected then "B" can join the connection as well. Third question: is there some sort of messaging apps for a lan ?? so "A" can send msgs to "B" without actually having to connect on the internet??
