That isn't how the guest account works, anybody who connects to your
share must be the guest user (remember that you don't have any users
and unknown users are mapped to the guest account by 'map to guest =
Bad User'). Now normally 'nobody' is the guest user and its group is
'nogroup', but you are using 'guest' with the group 'users' (this is a
bad move by the way). Because of all this and the way the share is set
up, all files and directories created in the share will belong to
'guest:users'

As I sort of said, having a share the way you have set it up, only
makes sense if you want/need a wide open share. Just about the only
way you could make it any less secure would be to allow wide links

Do you really need a standalone server ? or are the rest of the
computers in a domain ?
