Can't share files except Public files on Vista Systems

I have 3 Vista Ultimate computers. I followed all of the instructions in
File and Printing in Windows Vista article from TechNet. I still cannot share
ANY files outside of the Public folders on each computer. Public folder
sharing is working. I wish to share my user document, downloads, music,
pictures, and videos and not have to use the Public folders for sharing. I do
not want to have to copy all of my files to Public, I want to Share them in
place.

I have the password protection off in the Network and Sharing Center on all
of my computers. All have the same workgroup, Network name, network location
type is Private network, OneCare and firewall settings verified correct
settings for sharing. I have added Everyone and Guest accounts to all user
sharing computer folders.

I can see the folders from another computer. but cannot access them. When I
go to network user folder on another computer, I get a Access Denied message.
What can I do to share these folders?
