APIPA - Automatic Private IP Addressing
If no DHCP Server can be reached to obtain an IP-Address, Windows Vista will select one from the pool reserved for Microsoft. This IP-Address pool ranges from 169.254.0.1 to 169.254.255.254. No DNS, WINS, or Standardgateway will be assigned since this method was designed for small networks.
To disable APIPA open the Registry and go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
and create a key called IPAutoconfigurationEnabled and set it to 0.
