After update to .NET Framework 4.5.1 (through Windows Update). Some of our customers have reported errors is our application, specifically when it comes to SQL Server access.
The error is: “A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The message received was unexpected or badly formatted.)”
We found this problems occurs in some occasions, possibly in combination with SQL Server 2005 and Windows Server 2003.
Uninstalling .NET Framework 4 and reinstalling without update to 4.5.1 causes the problem to disappear, but this is not a permanent solution.
A search on internet revealed that the problem is happening more often and is known by Microsoft. Can anyone tell us if there is a more permanent fix for this issue, and if not when the permanent fix will be available.
Related threads mention the use of the command "netsh winsock reset". But this only seems to work for a few hours.
Thank you in advance for you assistance.
