====== Disable IPv6 On Windows ====== Make the following a registry file and then open or directly modify the registry. Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters] "DisabledComponents"=dword:000000FF After this change, the computer must be rebooted. I've also used this on Windows 2008 R2 as well without issues.
