DHCP replaces /etc/resolv.conf each time it updates ( using dhclient,
which runs when Network Manager asks for an IP or when your interface
comes up.

One way to stop this happening is to make a
file /etc/dhcp3/dhclient-enter-hooks that looks like this: 
( between the --------- lines )

---------------------------------------------------
#!/bin/bash

# Stop replacing /etc/resolv.conf !!

function make_resolv_conf {
echo “Doing nothing to resolv.conf”
}

---------------------------------------------------

Make that executable with  sudo chmod +x and your /etc/resolv.conf will
not change again ;)

Be aware though, that if you do this you need to be *sure*, of course,
that you do not want it to change at all.
