I'm trying to enable TLS_FALLBACK_SCSV on my IIS server on Windows server 2012 R2.
Some article's suggest creating a dword called UseScsvForTls with a value of 1 inHKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL
I've done this, and rebooted the server. But according to the test from ssllabs.com it's still disabled.
