My office has incredibly unreliable DSL service, but the odd thing is that the connection is fairly reliable, it's just that the ISP's DNS server is spotty.
We're running W2k8 and our own internal DNS server on it, but lately I'm starting to think I may have misconfigured it. Names resolve correctly if they are on the internal LAN, but the last time the ISP's DNS went down, external names were still not resolving.
At the time I did not have any forwarding configured; I assumed the server would automatically query the gateway if it did not have the IP cached, so I configured 188.8.131.52 as a backup DNS on the highest-level router. Now I've learned that I should have set up conditional forwarding all along on the server, so I did that and removed the entry from the router itself.
So, my question- I set up a conditional forwarding entry for domain "0.0.0.0" and listed Google DNS, Verizon DNS, and OpenDNS as master servers, but judging by the tutorials for doing this I'm questioning whether I set it up right. "0.0.0.0" isn't really a domain but what I'm trying to accomplish is to have one of those three services queried for all external name resolutions.
How would you configure W2K8 differently to achieve these ends?
