  • Question

  • Hi, 

    I have been getting this event ID: 36887 to disappear in the EventViewer Log however it's been there continuously.

    Event ID: 36887
    Source: Schannel
    Fatal Alert: 70
    Windows Server 2008 R2. 

    I did updated the TLS to 1.2 as advised: 
    https://support.microsoft.com/en-ph/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-wi

  • Hi,

    Fatal Alert 70 means “The protocol version the client attempted to negotiate is recognized, but not supported. For example, old protocol versions might be avoided for security reasons. This message is always fatal.”

    As far as I know, there have been many occasions where a event corresponding to SChannel is logged in the System event logs which indicates a problem with the SSL/TLS handshake and many a times depicts a number. And it can be relate to 3rd party software, browser, add-ins and etc.
