This was discussed here not very long ago.
>From /usr/share/doc/initscripts-8.45.30/sysconfig.txt:

      modify /etc/resolv.conf if peer uses msdns extension (PPP only) or
      DNS{1,2} are set, or if using dhclient. default to "yes".

So PEERDNS=no in the right /etc/sysconfig/network-scripts/ifcfg-<X>
should be your solution.
