did you /etc/init.d/samba restart? generally that makes changes to smb.conf happy happy. however, if you hadn't noticed, windows network neighborhood is sort of broken. try relogging into that machine (assuming you haven't.. somehow i don't see you keeping a windows box up for two days), after you've restarted samba. beyond that, it should be happy.
