Title: How to Create a System Data Source Name (DSN) in Windows XP

Objective: The objective of this demo is to teach you how to create a system data source name (DSN) in Windows XP. A Data Source Name (DSN) is the logical name that is used by Open Database Connectivity (ODBC) to refer to the drive and other information that is required to access data. The name is used by Internet Information Services (IIS) for a connection to an ODBC data source, such as a Microsoft SQL Server database. When you use an ODBC DSN entry to externally store the connection string values, simplify the information that is needed in the connection string. When you do this, changes are made to the data sources that are completely transparent to the code. Make sure that you create a system DSN. ActiveX Data Objects (ADO) does not recognize user (or local) DSNs. Because they store settings in the registry, system DSNs offer slightly faster performance than file DSNs, which store connection parameters in a file on your hard disk.
