I get a '[Microsoft][ODBC Microsoft Access Driver] Cannot open database '(unknown)'.' error when trying to access my ASP or ASP.net application

This error usually occurs if the MS Access database you are trying to connect to is of MS Access 97 or older format. The latest version of Microsoft Data Access Component is not fully backward compatible with Access 97 or older database formats. Your ASP or ASP.net page may work for a while after you first upload it but will produce this error over time.

Please contact support if you need help converting the database to Access 2000 format.

If your database is of Access 2000 format, it is likely that your database file is corrupt. Remove and upload the database file again should resolve the problem.
