Caution
If you are switching a computer from a statically assigned IP address to a dynamically assigned
one, it's recommended that you remove any statically assigned configuration information, such as manually
configured DNS or WINS servers. If you've specified a DNS server address on the DNS tab of the local computer's
network configuration, for example, this will override anything that was configured through DHCP options;
if this is not the effect that you had in mind, you should remove the manually configured information.

1-7. Configuring Automatic Private IP Addressing (APIPA)
Problem
You want to enable or disable Automatic Private IP Addressing (APIPA) on a Windows Server
2003 computer.
Solution
To disable APIPA for a particular adapter, create the following Registry value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
Tcpip\Parameters\Interfaces\
{<Interface GUID>}\
]
"IPAutoConfigurationEnabled"=dword:0
To disable APIPA for all adapters installed in a particular computer, create the following
Registry value—no reboot is necessary:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"IPAutoConfigurationEnabled"=dword:0
■
Note
If either of these Registry entries is not present, the operating system assumes a default value of
1
.
This means that APIPA is turned on and enabled on all Windows Server 2003 adapters by default.
