To disable automatic address configuration

1.

Open Registry Editor

 Caution

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer. You can also use the Last Known Good Configuration startup option if problems are encountered after manual changes have been applied.

2.

In Registry Editor, navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Tcpip\Parameters

3.

Create the following entry:

IPAutoconfigurationEnabled: REG_DWORD

4.

Assign a value of 0 to disable Automatic Private IP Addressing (APIPA) support.

5.

Close Registry Editor.

Note

To open Registry Editor, click Start, click Run, type regedit, and then click OK.

You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. 

If the IPAutoconfigurationEnabled entry is not present, a default value of 1 is assumed, which indicates that APIPA is used.
