Vista Networking Not Working…Can’t even ping localhost

I'm trying to fix a friends laptop running Vista. He told me his wireless networking wasn't working which I confirmed. I then tried the ethernet NIC and it also didn't work. I am unable to even ping localhost/127.0.0.1. I noticed when I issue an "ipconfig /all" command the assigned IP comes back with:

169.254.238.242 (Preferred)

My understanding is this comes back when the computer can't get an IP address using DHCP. I even tried assigning a static IP address (192.168.1.x for my home network) but no luck. I did some research and found this seems not to be an uncommon problem. I notice there are a lot of tunnels, etc. I'm not a big Vista guy so I'm not exactly sure what's going on here. I even tried upgrading the driver for the ethernet controller but no luck. I figure since it's happening with both wireless and the ethernet conroller it has something more to do with the the OS/dirver configuration. Here is the entire output of the ipconfig /all command:

You could try reinstalling the TCP/IP stack following these steps for Vista:

  1. Click on Start button.
  2. Type Cmd in the Start Search text box.
  3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator. Allow elevation request.
  4. Type netsh int ip reset in the Command Prompt shell, and then press the Enter key.
  5. Restart the computer.

The command will remove all user configured settings on TCP/IP stack and return it to original default state by rewriting pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to achieve the same result as the removal and the reinstallation of the protocol. The registry keys affected are:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
