DHCP and local DNS

Hi,

I have a DHCP connection to my ISP. My home LAN has been configured into my
local DNS. Each time I reboot the system, /etc/resolv.conf is overwritten
with the ISP's information only. How can I avoid the /etc/resolv.conf being
overwritten each time the system is rebooted?

My system is running Debian 3.0 (woody).

Thank you in advance for any help.
