Disable SSLv2 on IIS

Microsoft KB 187498 describes the registry values that can be used to disable various security protocols. Disabling SSLv2 is as easy as

reg add "HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server" /V Enabled /t REG_DWORD /d 0

This does require a reboot to put into affect.
