Weird DNS resolving issue

[Kevin Darcy]

Are the named.conf files identical? Do you use forwarding? To the same 
forwarder or different forwarders? Are you going through a firewall, and 
is the firewall configured with identical rules for the two nameservers?

As for the external DSL nslookup failures, that's probably just the 
combined effect of nslookup's idiocy about reverse-resolving nameserver 
addresses, plus the fact that the xxx.xxx.122.62 address doesn't 
reverse-resolve on the Internet. Using a real lookup tool like dig, 
which doesn't have this reverse-lookup "feature", avoids these kinds of 
problems.
