Disable Automatic Private IP Addressing - APIPA

,
APIPA is Enabled
APIPA sometimes is tricky, giving us IPs in a range of 169.254.0.1 to 169.254.255.254
When a DHCP server fails, APIPA gives you an IP address. The client then verify that it's address is unique on the network by using ARP queries. Whenever a DHCP server sends the DHCPOffer packet, the clients requests a dhcp lease, thus leaving the APIPA addressing.

The best way to solve this is by heading to the registry editor and change a DWORD value to zero.
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameteres
IPAutoconfigurationEnabled: 0
