samba network printing

Hello,
rh9 printserver, cups is configured perfectly, local printing works fine,
network printing does not. When i did the printer setup i just set up the
local printer, now i've installed samba3 via rpm and am trying to get
autodriver upload from windows clients working, this is not. Firstly, it
wouldn't save my settings, now when i go to that printer share to work with
it, i get some generic explorer protection fault error. Any ideas?
Thanks.
Dave.
