Hello I need some help bad. I am new to mac and have MacOSX. Im trying to connect to my 2 PC's for file sharing. One is XP the other Vista all on a wireless network. I thought I set up both PC's for file sharing but I guess I may have made a mistake down the line. But the biggy is every time I go to Finder on the Mac I dont see anything on the left side. Any help anyone!!
