This isn't working with Leopard and never worked with Tiger. I follow all of the steps in the guide. I made a shared folder on my Windows XP PC and got the internal IP address via ipconfig. I've tried connecting in Finder and the "Go"-"Connect To Server" menu. I called Apple Support and they were no use. I will be forever grateful to someone who can help me. Please guys? On a semi-related note- Don't you hate it when you call Customer Support and they say "Hi, this is George" in a ridiculously strong Indian/arabic accent. Im not a racist and have nothing against Arabs/Indians but come on, your name is Achmed or Toolip or something, not George. It's like the movie "Big Nothing". Also when I called, I could hear other support people talking in the background. Two different women with Arabic accents said, "Hello, this is Sheila."
