Are you perchance using dhcp on that box? ISTR I ran into that, don't
recall the distro at the time, but after fixing it 2 or 3 times, I finally
nailed that by fixing resolv.conf and then as root:
chattr +i resolv.conf
I expected something to complain, but nothing did and problem solved. It
is not a problem on the 10-04.4.LTS box and resolv.conf has not been made
I normally have all my local address's in the hosts file, nameserver points
at the routers local address, and order set hosts,nameserver.
I use dhcpclient only on the lappy, so the router, running dd-wrt on a
Buffalo Hipower, is set to act as a dhcp server.
