Hi,
I have 2 separate networks, each with a WS2012R2 server with Essentials Experience serving a few PC clients with Win8.1Pro.
Everything ran fine for the past few months. I was able to access the WS2012R2 servers dashboard via their remote web access sites.
Since Nov 18, I can no longer start the servers dashboard via remote web access. However, I can remote desktop to the PC clients via remote web access and I can start the dashboard from one of the PC clients.
There are no specific error or warning in the server event viewer logs.
In the remote PC event viewer logs, I found the following 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 10. The Windows SChannel error state is 10.
I couldn't find a resolution to this problem and it seems related to KB3011780.
Does anyone have an idea?
