A few times a day, it is not able to connect and the error mentions:
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement.
There is is large Microsoft article that suggests: To resolve this issue, upgrade the .NET Framework 4.5.1 to the Microsoft .NET Framework 4.5.2
Our SQL Server 2012 is running on VMWare and we have not been able to get much help from them even though we provided a lot of info that points to their implementation of the
vsocklib.dll being a non-IFS Winsock.
Have you guys ever had to deal with that particular scenario ? Has 4.5.2 this fixed the problem ?
