In a corporate / enterprise network where the DNS servers are Windows servers (domain controllers, in my experience, most of the time), the best thing you can do is stand up a few instances of <insert favorite DNS server here>, running on Linux, set them up as slaves for your internal zones, and point your users at those servers instead of your Windows servers.

You can also use stub zones to forward traffic for a single subdomain to your AD servers, while the other dns server handles recursive queries to the internet.
