i have a issue with the /etc/resolv.conf
everything works fine but when i reboot the machine the /etc/resolv.conf wil be changed and i have to update it again to let i works like i want to have it work.

I'm running Centos 5.4 Final
On the inet i read most of the systems have /etc/sysconfig/network/config to change
MODIFY_RESOLV_CONF_DYNAMICALLY
but i can find it

Does somebody knows how to change /etc/resolv.conf permantly so when i reboot it won't change anymore?
Thanx in advanced
