[Samba] How to I clean up Samba to start over?

[Boaz Bezborodko]

I've been working on setting up Samba, but after playing around with it
for some time and probably messing things up I'm getting all sorts of
permission problems.   Plus, when I look in Webmin, I find duplicate and
triplicate listings of Samba groups.

What I would like to is wipe it clean and try and start over since I now
know a lot more about what works and what doesn't.  But how do I do this?
