I have resolved the port issue by entering the SQL Server name as follows:
< Servername >,< portNumber >
I am not getting a connection timeout expired error while attempting to consume the pre-login handshake acknowledgement.
In investigating, and making modifications to the SQL server for possible solutions, many have suggested increasing the timeout for the application. Unfortunately, there is no way to do this in the Kentico Installer (that I know of unless you can upload it through the XML configuration option).
Any suggestions how to resolve this for the Kentico install?
