    I was stunned to learn my ISP was bought...though they deserve it, letting someone more competent take the reigns is probably a good idea. Still, when all the workstations shut down for the transition I was quite unaware until DNS started failing.

    One of the problems I uncovered was, upon pointing the forwarders to the new place, my main DNS machine is quite unable to stand on it's own...and I had to fake the recursion I need to resolve "google.com". The local zones resolve in both directions, quick as lightning.

    I spent about 20-30 hours on it; the local zones are *perfect*, the various combinations of "recursion on" and "allow-recursion" as permissive as I could possibly make them did nothing to solve the problem.

    Guys- check your DNS. "nslookup" to your Dapper BIND servers, ask them to resolve "www.google.com" and see what you get, if anything. I'm betting your workstations are set to use the local DNS, and then the ISPs. If this is a bug, I'd like to ask around before reporting it.
