Mac OS X joining Windows XP network help needed
 

I just got a new Macbook Pro, and I've got most of my network problems figured out except one: I can't get shared folders to show up on either my Mac or my PC. I can join the wireless network fine and access the internet, and I can also share my PC's Itunes library with my Mac's Itunes, yet I can't figure out how to share files between the two.

I did a little research, and it seems I have things set up correctly. My PC (running Windows XP Pro) has sharing enabled, and I have several shared drives which I can access fine with my other PC's on the network. But nothing shows up in the network portion of my Mac.

Anything I'm missing? Thanks for the help.
