Completely disable IPv6 on Windows Server 2008 and Windows Vista

To completely disable IPv6 on Windows Server 2008 and Windows Vista, it’s not enough to just uncheck the IPv6 setting in you Network Adapter’s properties. Type ‘ipconfig/all’ in an administrative command prompt and you’ll see what I mean.

To completely disable IPv6, create the DWORD (32-bit) registry key DisabledComponents in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\

and give it the value ‘FF’. This will show as 0x0000ff (255).

Reboot the machine and type ‘ipconfig/all’ in an administrative command prompt and you’ll see your IPv6 settings are gone.
