Disable IP Autoconfiguration in Win XP?

By TomSal ·
How can I permanently disable the IP Autoconfiguration "feature" in Windows XP Pro.

I have an executive using XP on his laptop and it keeps screwing with this wireless connect because it constantly is autoconfiguring the IP info for his wireless interface.

I'm a little confused (which isn't unusual). Are you referring to scanning for available wireless networks or DHCP (automatic IP address) in IP settings for adapter?

The adapter driver/software settings can usually be configured to connect only to a single wireless network.

IP settings can be entered manually and should stay put unless "Obtain an IP Address Automatically" is checked.

Hope this helps some. Feel free to provide additional info.

Thanks for your input. I'm well aware of the information you provided. That's not what I'm referring to however. In Windows XP (and I believe MS first started it with Windows 2000) there is a "feature" of the OS called IP Autoconfiguration. What this does,aside from be annoying, Windows assigns a default addressing scheme for any network interface that has problems retrieving one from the LAN/WAN. There is a way to disable it in the registry, I just forgot how. Once its disabled Windows will no longer force the autoconfiguration address on an adapter.

Checked Technet.com

You can also disable automatic private IP addressing for a given adapter (but not DHCP) by editing the registry.
You do this by adding the registry entry IPAutoconfigurationEnabled with a value of 0x0 (REG_DWORD data type) in the following subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \Tcpip\Parameters\Interfaces\<adapter>

Use a registry editor to add this entry, then shut down and restart the computer.

This registry entry is specific to each adapter. If multiple adapters are installed, you can disable APIPA for all installed adapters by setting the value of the IPAutoconfigurationEnabled entry to 0 (REG_DWORD data type) in the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \Tcpip\Parameters

Hope that helps

This is for the Automatic Private IP Addressing (APIPA)thing. Think this is what you are talking about.

I solved this on my own, but it would be wrong not to give you points because I forgot to close the question after you did research. Thanks. (This is the information I found as well).
