SSMS and .Net Framework 4.5.1
Posted by decipherinfosys on March 31, 2016
Ran into an issue yesterday. Installed the .Net Framework 4.5.1 on my laptop and post that, SQL Server Management Studio failed to connect to any of the instances. The error received was:
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.)
You can uninstall .Net Framework 4.5.1 and install .Net Framework 4.5.2 in order to fix this. Or if you need to keep the .Net Framework 4.5.1, there is a workaround available which is listed on Microsoft Connect page here.
