I used the Control Panel to edit smb.conf ... so, when I looked at the file earlier, it was already updated.

However, I did try all instances of the samba binary unsuccessfully at that time too --- whether in /usr/local or /usr/share or the third location which I can't remember where it was. All returned a permission denied error.

When you say the startup scripts weren't included, you're not saying that I also need them to run samba, right? I mean I don't need them because, theoretically, I would just type /usr/local/samba start to get the service going. (Which unfortunately isn't working.)
