Networkping
I am on os x 10.9.4
If I ping google from the network utility I get 0% packet loss.
But if I try to ping google from the terminal with ping www.google.com I get 100% packet loss. System Preferences -> Firewall shows it is turned off.
What else might be happening?
So, Broken MBP can ping anywhere, including other machines in your network, but can it ping itself? (You have to read that with the "Will it Blend?" sound)
The rest of the machines can ping each other, but not the Broken MBP.
Am I correct?
Does this only happen via Wi-Fi? Have you tried using a Cable?
What happens if you turn ON the firewall and make sure that in "Advanced" the machine is not in Stealth Mode:
(Security -> Firewall -> Advanced)
Well, did you read the comments at the top of /etc/resolv.conf?
# Mac OS X Notice
#
# This file is not used by the host name and address resolution
# or the DNS query routing mechanisms used by most processes on
# this Mac OS X system.
The correct solution is to add the search domains via the Network panel in System Preferences as described here.

What is the error message you get when you are pinging from the terminal?
try an nslookup www.google.com and make sure that your dns is resolving correctly
