I see other samba_dlz entries of a positive nature. Thoughts? (Could this have anything to do with my recent dns issue? Is some record missing?) -- _______________________________ Bob Wooden of Donelson Trophy "Everyone deserves an award!!"

The PTR are properly registered by client computers on recent samba version, but you have to create the reverse DNS zone beforehand.
