Change TCP/IP Broadcast Address (Windows NT/2000)

This setting allows Windows to be configured to use zeros-broadcasts (0.0.0.0) instead of ones-broadcasts (255.255.255.255). Most systems use ones-broadcasts, but some systems derived from BSD implementations use zeros-broadcasts.

Open your registry and find the key below. For Windows 2000 instead use the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Tcpip\Parameters\Interfaces\[Adapter ID] key.

Create a new DWORD value called "UseZeroBroadcast" and set it to "1" to enable 0.0.0.0 broadcasts.

Restart Windows for the change to take effect.
