Problem:

When you configure the ODBC data source, you get the error:

Connection failed:SQLState: '28000'SQL Server Error: 18452[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'gbadmin'. Reason: Not associated with a trusted SQL Server connection

Solution:

You didn't choose Mixed Mode Authentication during installation. To set up mixed mode authentication:

Go to Start > Programs > Microsoft SQL Server > Enterprise Manager.
Expand the tree until your server displays.
Right-click your server name.
SQL Server Properties (Configure) displays.
Choose the Security tab.
In Authentication, choose SQL Server and Windows.
Click OK.
Click Yes to restart Microsoft SQL Server.
