Samba WERR_ACCESS_DENIED

Well, I do have a samba.conf (see below) and I have gone through a bunch of sources to try to identify what is wrong. WERR_ACCESS_DENIED seems to be a permissions issue, not a configuration issue, but I’d sure appreciate any review of the .conf file to see if anything is wrong there that could be driving it.
