Hello I am having problems getting the computers on my net work at home to share printer and files. The first system is running xp home and is an amd 3400+ 64 bit, The second computer is an amd 2400+ running xp pro, and the third is my laptop and it is a amd sempron 3800+ running xp media center edition. they all share an internet connection through a dsl router. two are wireless and the third is wired to the router. we can play games on the net work I have run the net working wizard that comes with windows and told it to allow printer and file sharing but it doesn't work. what am I doing wrong? or is there some sort of additional software that i can purchase to take over for windows networking software?
