dhcpd error - IF host.myisp.com.br IN A rrset doesn't exist add: timed out

[Paulo Fonseca Jr.]

Hi,

I'm receiving the folowing error when a windows machine to try a connection 
with internet through freebsd adsl (ppp) gateway: "IF windows.myisp.com.br IN 
A rrset doesn't exist add windows.myisp.com.br 300 IN A 192.168.0.3: timed 
out." I'm not running a dns server on freebsd gateway. I'm using a dns server 
from my ISP.

My dhcpd.conf:
 option domain-name "myisp.com.br";
 option domain-name-servers 200.215.1.3;
 ddns-update-style ad-hoc;
 log-facility daemon; 
 option routers 192.168.0.1;
 subnet 192.168.0.0 netmask 255.255.255.0 {
  range 192.168.0.2 192.168.0.254
 }

In my rc.conf:
 ...
 ifconfig_xl0="inet 192.168.0.1 netmask 255.255.255.0"
 dhcp_options="xl0"
 dhcpd_enable="yes"
 ...

Anybody can help me!

thanks!
