This is a two-part inquiry that likely one person can solve.
I currently use two BIND servers for Primary and Secondary DNS. They both answer requests fine and good, have done so for many months. Today, I'm trying to resolve a quirk. Any queries to these BIND servers come back as non-authoritative. How do I go about resolving this? I own this and many, many other domains.
Second, I'm fixing to move one domain to AD. Would I actually be better off leaving that domain on BIND, then use a .local domain for AD?
