This message usually means there is a problem with the driver you are using, the path to the database is incorrect, or file permissions on the database are set incorrectly.
You should make sure you have the latest MDAC drivers installed, as well as check your path. Also, if you have tried to open the database using MSAccess, and now get this error you may need to restart the IIS service.
