Bizzare File Sharing Issue: Can Only See My Public Folder, Not Others

None of my shared folders besides my Public folder are showing up when looking at my network shares from other computers. I've checked folder permissions, folder owners, my firewall, my router (made an ad-hoc network), and I've tried the almighty repair permissions.

I've tested this over SMB with a Windows7 RC1 computer and a Vista SP1 computer, and with other Macs running an various versions of OS X and the results are still the same. The only odd software I have installed is Parallels.

Anyone have an idea what's going on here? This is pretty weird.

Bumping my own thread because I have numerous posts for this same issue around the internet with no solutions.
