Vista won't share subfolders

Hi,

I am trying to share a "My Music" folder on my Vista Home Premium machine.
It shares only the top-level My Music folder but no subfolders. I have tried
to make subfolders inherit permissions from My Music but to no avail--they
still come up not shared, even when I add "Everyone" and "Full Control" to
the permissions of the My Music folder.

In short, how does one get sharing to apply to all subfolders? For me, the
folder My Music has over 1000 subfolders, and so it would be impossible
(practically) to share them all separately.

Thanks for any thoughts.
