No. Resolution of domain names is done by libc under the same user id as
the program that is being run (ie it is not done by the kernel). This
implies that the config files in /etc that you have mentioned below

Try:
ls -l /etc/nsswitch.conf /etc/resolv.conf /etc/host.conf
and see if anything looks suspicious. If you aren't sure yourself,
then send a copy to this mailling list.
