Exchange 2013 CU6 (15.0.995.29) is running on Server 2012 R2
started logging Schannel errors very frequently (8 errors every minute) in the system event log.
System performance is degraded
If issue IISRESET /STOP, the errors stop.
If I disable the NIC the errors stop.
"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 10. The Windows SChannel error state is 10."
What approach could be used to identify the root cause of this error?
