That damn 169.254.x.x IP address has caused me more headaches than I care to count. Here’s how I turn it off:

  1. Open up registry and go to HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
  2. Add REG_DWORD of IPAutoconfigurationEnabled with a value of 0 (zero.)
  3. REBOOT!

 

Seriously, you can also apply that command down @ the adapter level too. Typically when I’ve got a problem w/ APIPA¬†I’ve got a bigger issue but can’t see it yet. As an example, once I turned off APIPA on a laptop I could see that the OS just didn’t like the static IP address I was trying to configure it with. Once I changed the IP to something different, it worked just fine. GO FIGURE!
