FYI, these are two different problems.  The first implies the second,
but the second does not imply the first.  If name resolution is broke
yet you can ping an external IP address, that proves that it's not a
network connection problem.

I do DHCP at home all the time, my DNS Servers field always come up
blank, yet DNS works for me just fine.  When OS X connects via DHCP,
it automatically populates /etc/resolv.conf with the DNS settings
provided by your DHCP server.  Apparently, these settings are not
displayed in the Network system preferences.  Now if /etc/resolv.conf
comes up blank, then there's something broke with your DHCP server.
