I got my PC and MAC to share! haha. altho my PC cant access my mac my mac can access my PC and i cant take things and put things on it. which is good enough for me. very very glad!
so do you want it the other way around?
if you do, go to system prefs. and go to sharing.
then enable file sharing.
that window should also tell you where to find your mac. ex: afp://youripaddress.
then navigate to that folder in windows explorer. and voila.
