I'm seeing the following pair of errors in eventvwr on Windows Server 2008 R2: "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. Ran across this post while researching 36888 and 36874 events from SChannel on one of our Windows 2008 R2 servers. I decided to dig into KB2992611, mentioned in another answer. 36888 is a failed SSL conection request on TLS 1. 2 - none of the cipher suites supported by the client app are supported by the server.

The desktop app, using SCHANNEL_ALERT_TOKEN, generates a SSL or TLS alert to be sent to the target of a call to either the InitializeSecurityContext (Schannel) function or the AcceptSecurityContext (Schannel) function.

CAUSE: Schannel supports the cipher suites. The suites are listed in the default order in which they are chosen by the Microsoft Schannel Provider. As I understand it, the errors are causes by devices connecting with old ciphers, that are not accepted by our server. Until recently, the cipher stack was set to the server default but after an SSL Labs audit, we decided to remove some of the more outdated ciphers, which allowed us to attain a grade 'B' status. Good morning, everyone. Both of my DCs are getting these errors, and I am at a bit of a loss to explain it. The errors always show in pairs but do not appear at a regular interval. For example, the errors were logged at 10:21:36 AM. Then, at 10:22:39 AM then were logged again.
