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.
In Registry Editor, navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Click the Parameters folder, and then click Edit.
Click New, and then click DWORD Value.
Type the following to create a new entry:

IPAutoconfigurationEnabled
Right-click the new entry, and then click Modify.
In Edit DWORD Value, under Value data, ensure that the setting is O.
Exit Registry Editor, and restart the computer.

Notes

To perform this procedure, you must be a member of the Administrators group or the Network Configuration Operators group on the local computer. For more information, see Default local groups and Default groups.
To open Registry Editor, click Start, click Run, type regedit, and then click OK.
If the IPAutoconfigurationEnabled entry is not present, a default value of 1 is assumed, which indicates that APIPA can be used.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
