File DSN's Page 2
Steps to create a file DSN source.(This example will connects to an Access Database)
Open up a text editor and create a file named WEB.DSN
Type in the following:
DRIVER=Microsoft Access Driver (*.mdb)
Save this file in the root directory of your web application. Notice that I dont give the default drive and DBQ within the actual file DSN, this is so that I can reuse the DSN for every Access DB which I need a connection to.
