Hi,

At least one of them must have a forwarder or root hints setup.

There are multiple ways to achieve that
Setup dns forwarders on these dns server
The forwarder servers should be public dns servers such as Google dns
Provide them direct internet access and they can use root hints to find external addresses

If I remember correctly (how I was taught anyway) your local DNS information first hits your Primary DNS, then your Secondary DNS, then, when all else fails, your router is asked and it resolves as long as it has internet access. @Dr. Klahn has a good article for quick reading, but for indepth reading that stays focused, you could always try a Network+ book. I like the dummies series to a point, but sometimes you need that extra verbiage to help flip the "Ah Ha" switch.
