Event ID 36888 & Event ID 36874 Schannel RRS feed

  • Question

  • Hi,

    I have a Windows Server 2012 R2 Standard machine, its being used as an Edge server for Skype for Business 2015.  I have several of the following errors:

    Source: Schannel

    Source: Schannel
    Event ID: 36888
    A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 40 The Windows SChannel error state is 1205.

    Source: Schannel
    Event ID: 36874
    An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server.  The SSL connection reqruest has failed.

    Lastly this warning is poping up too:

    Source: DNS Client Events
    Event ID: 8016
    The system failed to register host (A or AAAA) resource records (RRs) for network adapter.

    This server again is an Edge Server for Skype for Business so its in the DMZ of the firewall.  Also it only has Skype for Business and SQL Server 2014 loaded on it.  Is the DNS warning connected to the others? What causes the other errors?
