One common issue in dealing with Access is that if a user opens the database via the Access GUI, it is locked and you cannot open a connection to it via ASP.
If you have it open for development, you need to close Access before testing your ASP page. If other users have access to it, you should place it in a restrcited directory that only your ASP has rights too.
If this is not your issue, please provide more info about your application environment and how Access is being used or is setup.
