I have a Mac Pro running OSX 1.5.2 and Win XP on bootcamp plus a Win XP PC upstairs. The Mac connects to my wireless router with an ethernet cable and the upstairs PC uses a usb wireless adapter. When I am running Windows on my Mac, I have been able to set up file sharing and printer sharing without any problems, but I can't get anything to share when I am running in OSX. Can anyone please shed some light on how to do this or point me in the right direction to find the information that I need to get this to work? I thought that things were supposed to be easier on a Mac. Thanks for any help.
