I think what we're looking at is the excellent "map archive" smb.conf 
directive here, which maps certain UNIX permissions to DOS style
attributes. Try man smb.conf(5) and search for the map xxx directives.

There's the "map archive", "map hidden" and "map system". I too needed
this when IExploder wouldn't set the profile if the directory wouldn't be
of type system or something like that. It's all in the man page - I hope
you know a little bit about file permissions and umasks, etc.

Hope to help,
