Add server variables to capture SSL/TLS protocol


  • I'm running Windows Server 2012 R2 and I'm trying to configure IIS logging so I can monitor the protocols being used to connect to the server.  I've found some articles on how to set it up but when I try to add the server variables in IIS logging, I don't see CRYPT_PROTOCOL, CRYPT_CIPHER_ALG_ID, CRYPT_HASH_ALG_ID, or
    CRYPT_KEYEXCHANGE_ALG_ID listed as options under the Source field when I select Server Variable as the Source Type.  One article mentioned that the variables were added as part of the KB4025335 update.  I don't have this update installed on the server but when I try to install it, I get a message "The update is not applicable to your computer".  Any ideas on how I can get the protocol variables to show up?

  • Thanks for the info.  I was able to install updateKB4338815 and rebooted but I still don't see the server variables I'm looking for.  Not sure if it matters or not but I'm running Exchange 2013 CU 19 on this server as well.
