Question really weird DNS issue. Help needed ASAP!

We are a top level domain company. Due to some employees departing, I just inherited control of some root servers. All seems to be working just fine except for one problem.

A customer updated their sites' nameserver information. Our zone file reflects the change, but all ns queries fail. If I cat the zone file, it has two records for the zone and both are correct. But an nslookup or dig of the local nameserver returns "NX domain". I've restarted named, tried an "ndc reload", and even rebooted the server itself. Everytime, same problem... it's as though it's caching it's information somewhere, but not in RAM (since it would be purged on a reboot).


[root@dns1]:/usr/local/named/db# grep zone.db 6H IN NS 6H IN NS

[root@dns1]:/usr/local/named/db# nslookup
Server: dns1.localhost

*** dns1.localhost can't find Non-existent host/domain

I am thoroughly confused and need any help/suggestions available as the domain is owned by my boss and he wants it fixed ASAP.

wild guess

Make sure that their nameserver is allowing queries and zone transfers. I had a similar problem with one of my nameservers and it turned out that it was not allowed to axfr from the master server.

Funny though, because BIND will say "oh I just transfer from there" [transfer fails] "now I should have a copy here" [no copy] "no such domain"
