The built-in Samba in Mac OS X works flawlessly...it took me a while to figure it out...but it works perfect now...all you have to do is download the Samba Server Configuration Tool from versiontracker.com to set up the shares and you'll be set. You don't need any of those other apps. If you want to do it, PM me and I'll walk you through it...You can set up multiple shares on multiple discs and hide invisible files, the whole 9 yards...it's the way to go...
