problem in DNS server

[nvarma at in.ibm.com]

Hi,

  I have recently configured DNS server on IBM RS600 machine running with
AIX4.3.3 Bind level 8.2.3.

This is the portion of the named.conf file...

options {
        directory "/etc/nameserver";
        forwarders
{9.14.1.30;9.14.1.2;9.185.94.240;9.36.2.99;9.185.129.112;};
};


During nslookup using this server, some of the domain names are resolved
properly.
 But some of the domain names return with error like Non Existent Host /
Domain.


Could someone please help me resolving this problem?

Regards

Nischal
