Robb -

Since your AD domain controllers are critical to the infrastructure, you
hopefully will have more than one. In that case, have all your DCs run
DNS in AD-integrated mode as well, and that should take care of your
redundancy issues. We also have BIND at the root of our domain,
delegating the necessary zones to Win2K DC/DNS servers, and so far
everything has worked just fine, except for some minor issues with
reverse lookups. If your AD environment can use a completely separate
address space from your BIND environment, you'll save yourself some
headaches with the reverse lookup setup.
