To access the Administrator:
On the Windows desktop, select Start, then Settings, then Control Panel to open the Control Panel window.
In the Control Panel window, double-click the Administrative Tools icon, and then double-click the Data Sources (ODBC) icon to open the ODBC Data Source Administrator dialog box.
In the ODBC Data Source Administrator dialog box, click the System DSN tab.
