Default DNS Configuration issue

Hi,
i am having a DNS issue in my configuration.
My Linux box is CentOS release 5.5. It is bundled with SIPfoundry sipXecs and connected to a router which links the machine to our isp. During the installation, the isp's DNS IP was provided when the installation asked for the DNS ip. But now the DNS seems not to function very well when a Diagnostic Configuration test is ran from the sipXecs admin page.

The error below was seen.

(A)
SIP route to SIP_DOMAIN_NAME does not match the configured IP address.

See the installation guide on setting the DNS SRV records and domain names.


SIP route to SIPXCHANGE_DOMAIN_NAME 'esofties.com' is not to my IP address: 192.168.1.9
See the installation guide on setting the DNS SRV records and domain names

(B) The DHCP test also gave the error below

Missing mandatory DHCP configuration parameters.

The DHCP server responded with an IP address assignment but did not include one of the mandatory network configuration parameters. Please see the test log for further details.

(C)
My /etc/named.conf file looks like this

// WARNING: Name server configuration is a sipX automatically generated file.
// Contents may be overwritten unless you change the mode to "Manual".
// Available modes:
// "Master" - Master name server (on primary server).

//

options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
forwarders {
192.168.1.1;
};
forward only;
};


Please can anyone help me out here. I don't really know how to make this work. thanks
