The response below is of course absolutely correct.    

One thing to point out -- Since you are running DHCP on the cobbler 
server, this would be an excellent time to try out cobbler's dhcp 

Just edit /var/lib/cobbler/settings to change manage_dhcp to '1', then 
edit /etc/cobbler/dhcp.template to include the correct dhcp setup 
information -- just replace any IP addresses that are wrong and leave 
all the "$" fields as is, as cobbler will template those out for you.    
Then run "cobbler sync".    Cobbler will now be managing your dhcp 
configurations, so whenever you add a system in cobbler, you can also 
specify the IP address it will get (optionally) and  you won't have to 
hand edit your dhcpd.conf file again.
