This looks like it is a permissions problem. Make sure you give the IUSR account (or whatever account ASP.NET runs as) read/write permissions to your database.

you can try :here copied from there :

• This commonly occurs when your database file is opened exclusively
  by another application (usually MS
  Access). Close all applications that
  use this database and try again.
• This error may occur if the account being used by Internet Information
  Server (IIS), (usually IUSR), does
  not have the correct Windows NT
  permissions for a file-based database or for the folder containing the
  file.
• Check the permissions on the file and the folder. Make sure that you have the ability to create and/or destroy any temporary files. Temporary files are usually created in the same folder as the database, but the file may also be created in other folders such as /Winnt. If you use a network path to the database (UNC or mapped drive), check the permissions on the share, the file, and the folder.
• Check to make sure that the file and the data source name (DSN) are not marked as Exclusive.
• Simplify. Use a System DSN that uses a local drive letter. Move the database to the local drive if
  necessary to test.
• The "other user" might be Visual InterDev. Close any Visual InterDev
  projects that contain a data
  connection to the database.
• This error may also occur when accessing a local Microsoft Access
  database linked to a table where the
  table is in an Access database on a
  network server. In this situation,
  please refer to the following article in the Microsoft Knowledge Base for a workaround: Q189408 PRB: ASP Fails to Access Network Files Under IIS 4.0
