In that case, someone smarter and more knowledgeable on this list will hopefully help you. But first - one last suggestion - if you find that forwards to 3rd party servers work - but turning those off causes issues - you should probably make sure that your "root hints" are updated, and purge any caching (rndc flush), then restart BIND. Maybe you've already done that? But if not, it's worth a try before digging deeper. If that doesn't fix this, then hopefully someone else on this list can help you.
