Networking (here i see it, there i don't)

[hdbg62]

I am totally lost with this. I have a PC (Ultimate) & Laptop (HP), networked through a Linksys which works fine with both cable and wireless connections and have all sharing options enabled on both machines. The problem is that while I am able on the Laptop to view all of my PC's user folders under "USER", I can only view the Public and Default user folders under "USER" from my laptop on my PC. I double and triple checked the Properties for the USER folders on both machines and they are set the same. Both are fully shared, show the correct network path but while on the laptop properties/advanced sharing/permissions it shows "EVERYONE" and "ADMINISTRATORS", it only shows "EVERYONE" on the PC. I don't understand why I can't see what I got set up to see on the Laptop but not on the PC.
