You "copied over the zone files". However, the bind 9 server is
responding with NXDOMAIN. It appears to me that the server does not
believe it is authoritative for the zone. Verify that the server indeed
believes it is (look at the logs on startup). Take a look at your named
configuration to make sure you are properly including the zone file into
the configuration.

All,
Have two servers. One has BIND8, the other BIND9.
Copied over the zone files from the BIND8 server to the BIND9 server,
so they are identical.
Updated the /etc/resolv.conf file and the named.conf file.
When I do an nslookup (from a third server) pointing to the BIND8
server, it works fine:
# nslookup
> server 10.179.193.6
Default server: 10.179.193.6
Address: 10.179.193.6#53

When I do the same pointing to the BIND9 server, it doesn't work:
# nslookup

Also did a dig pointing to the BIND8 server:

On BIND 9 server, get the following:

Any idea why the query to the BIND9 server would not work?
What should i look for?
