One computer is viewable, the other is not

Hi,

I recently set up a wireless network with my laptop and desktop. From the desktop, I can see and enter any files that are on my laptop. From my laptop, I can see and enter my desktop via the users folder, but when I enter it only has the generic "public folders" rather than the actual C: drive. On Network & Sharing, they both have file sharing, network discovery, public file sharing, and printer sharing set to the on position. I am using McAfee on my laptop and AntiVir on my PC. Any thoughts on how to see the files from my PC on my laptop? I wanted to transfer some of them over and don't want to have to use a memory stick.

Thanks.
