    Who owns the External DNS server?
    Who will use it?

    IMHO, unless you are a big company like Microsoft, let someone else be the nameserver for your external domain DNS, and manage your internal DNS through AD
    If you run your own nameserver, you have specific responsibilities to ensure resolution is available.

      It also means you need to be well patched and be very secure since "owning" a DNS server can be mighty handy thing for spammers and other malicious Net users.

      I would suggest using the DNS of your company's ISP or the DNS of the provider who holds your Domain Name Management Console (if you have one).
      1 1 was a racehorse.
      2 2 was 1 2.
      1 1 1 1 race 1 day,
      2 2 1 1 2

        We host our own but I don't see a point unless you are a particularly large company. It should at least sit in a DMZ and it doesn't want to be a domain member, generally speaking it is not Microsoft DNS as well, at least in my experience.
