Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement.

I received the following error when trying to connect to a server's SQL Server. I was able to telnet the Server on the required TCP Port (1433) but SSMS could not connect to the SQL Server instance. 

 Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was – [Pre-Login] initialization=13472; handshake=14425; (Microsoft SQL Server, Error: -2)

 I eventually found that a Hyper-V Adapter was responsible for the issue, disabling which resolved the issue, have faced a similar issue with VirtualBox adapter too.

Hope it helps.

If you do not want to disturb the standard layouts its better to copy one of the existing layouts and then modify it using the designer. Please note the designer only opens in Internet Explorer so it will save you time by not trying to open it in other browsers e.g Chrome 2. Next we need to add this layout to the Store where we intend to use it, in
