MS SQL Server Concepts and Programming Question:

Continue from the previous tutorial. After clicking Next on the SQL login information screen, ODBC manager will try to connect to the SQL Server with the login information you provided.

After a period of waiting time, you may get error message box saying that:

Connection failed:
SQLState: '01000'
SQL Server Error: 53
[Microsoft][ODBC SQL Server Driver][DBNETLIB]
ConnectionOpen(Connect()).

Connection failed:
SQLState: '08001'
SQL Server Error: 17
[Microsoft][ODBC SQL Server Driver][DBNETLIB]
SQL Server does not exist or access denied.

See the picture below:
ODBC DSN Connection Failed

Three possible reasons for the failing:

* Wrong server name - You provided an incorrect server name.
* SQL Server not configured to take a network connection - You need to check the SQL Server configuration.
* Wrong login name or password - You provided incorrect login name or password.

The first and third reasons are easy to validate and correct. The second reason requires further investigation. Continue with the next tutorial to configure your SQL Server to take a network connection.
