Error in the query designer

The system cannot find the file specified

----------------------------

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

                               

Reason: Query string’s error. Is either the user id and password incorrect or the connection string is not correct.

I changed to use this connection string instead of the one suggested in the Microsoft tutorial. I used this : Server=MSSQL2008;database=Training;

Then, I am able to see this:
