newbie: some A records don't work? (short name)

[Jean-Christian Imbeault]

I'm sure there is a really simple answer to this question. So simple in fact 
that I can't find it on the mailing list or in the BIND book.

I have a DNS server server set-up on our LAN. I've set it up to use a 
non-existent sub-domain of our registered domain so that users can access 
LAN machines by name instead of IP. So far it's worked fine for the test 
machine but I have started adding new A records and they aren't working.

Here's my problem. Our registered domain is mycompany.co.jp. I've decided to 
use intranet.mycompany.co.jp as the sub-domain for the LAN and to forward 
any queries the local LAN DNS server can't answer to our ISP's DNS servers. 
The local server is on a machine called intranet, so 
intranet.intranet.mycompany.co.jp.

To save some typing I have also added an A record for just 
intranet.mycompany.co.jp to point to the same IP as 
intranet.intranet.mycompany.co.jp

So far this has worked. I have added another A record for another machine 
and it works also as long as I use the form 
machinename.intranet.mycompany.co.jp ... If I try to use the shortened 
version, i.e. machinename.mycompany.co.jp it doesn't work. This "shortened" 
name "trick" only works for the machine the DNS server actually sits on 
(maybe it's because the machine has the same name as the sub-domain?)

Can anyone explain to me why I am seeing this "problem" and how I can 
correctly configure my DNS server to respond to "shortened" names?

Thanks!

Here is my conf file and forward file.

[root at intranet named]# cat /etc/named.conf
options {
        directory "/var/named";
         query-source address * port 53;
         forwarders {
             165.76.16.2;
             165.76.8.2;
         };
};
controls {
        inet * allow {any;} keys {"rndc-key";};
};
key "rndc-key" {
        algorithm hmac-md5;
        secret "bGV0bWVp";
};
zone "intranet.mycompany.co.jp" {
        type master;
        file "db.intranet.mycompany.co.jp";
};
zone "100.2.10.in-addr.arpa" {
        type master;
        file "db.10.2.100";
};
zone "0.0.127.in-addr.arpa" {
        type master;
        file "db.127.0.0";
};
zone "." {
        type hint;
        file "db.cache";
};
