Bind and AIX

I am attempting to set up bind on an AIX 5.3 machine. I ahve created a named.conf, db.cache (for root domain and hint file) and a db.domainname file for the host entries. However, when I set my pc to use the AIX box as it's dns server, I can not resolve names. Is there anything obvious maybe I am missing in the setup? Other than the named.run file, are there any other logs files I can check?

Below is my named.conf

options {
directory "/etc";
};

zone "testdomain.com" in {
type master;
file "db.testdomain";
};

zone "." {
type hint;
file "db.cache";
};

here is my db.testdomain

testdomain.com. IN SOA dns.testdomain.com. 1 (
10808
3600
604800
86400
)
;
;Name servers
;
testdomain.com. IN NS dns.testdomain.com.
;
;
;
localhost.testdomain.com. IN A 127.0.0.1
test.testdomain.com. IN A x.x.x.x
test2.testdomain.com. IN A x.x.x.x
test3.testdomain.com. IN A x.x.x.x
