Answer 1

Typically, to troubleshoot this, you go to SQL Server Configuration Manager (SSCM) and:

1. ensure Shared Memory protocol is enabled
2. ensure Named Pipes protocol is enabled
3. ensure TCP/IP is enabled, and is ahead of the Named Pipes in the settings

Maybe it can help: Could not open a connection to SQL Server

Note : If this is a new instance of SQL Server be sure SQL Server and Windows Authentication is enabled

1. Right Click the Server in SSMS and pull up server properties
2. Go to Security--> Select 'SQL Server and Windows Authentication Mode'
3. Restart the Server and Login with the credentials

Answer 2

I had this same error message, turns out it was because I didn't have mixed mode auth enabled. I was on Windows Auth only. This is common in default MSSQL deployments for vSphere, and becomes an issue when upgrading to vSphere 5.1.

To change to mixed mode auth you can follow the instructions at http://support.webecs.com/kb/a374/how-do-i-configure-sql-server-express-to-enable-mixed-mode-authentication.aspx.
