I can't seem to work out why my DNS isn't working properly, if I run dig from the nameserver it functions correctly:

# dig ungl.org

; <<>> DiG 9.5.1-P2.1 <<>> ungl.org
;; global options:  printcmd
;; Got answer:

but when I run it from another server in the same datacenter I receive:

# dig @87.98.167.208 ungl.org

my zone file for this domain is

$ttl 38400

                201003121

localhost.      IN  A   127.0.0.1
www             IN  A   188.165.34.72

and the named.conf.options is default:

options {
    directory "/var/cache/bind";

    // If there is a firewall between you and nameservers you want
    // to talk to, you may need to fix the firewall to allow multiple
    // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

    // If your ISP provided one or more IP addresses for stable 
    // nameservers, you probably want to use them as forwarders.  
    // Uncomment the following block, and insert the addresses replacing 
    // the all-0's placeholder.

    // forwarders {
    //  0.0.0.0;
    // };

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { ::1; };
    listen-on { 127.0.0.1; };
    allow-recursion { 127.0.0.1; };
};

named.conf.local:

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
// include "/etc/bind/zones.rfc1918";

zone "eugl.eu" {
         type master;
         file "/etc/bind/eugl.eu";
         notify no;
};


zone "ungl.org" {
         type master;
         file "/etc/bind/ungl.org";
         notify no;
};

The server is running Ubuntu 9.10 and Bind 9, if anyone can shed some light on this for me it'd make me very happy!

thanks
