ASP page interacting with MS Access database file ('.mdb') displays the following error:

    Microsoft JET Database Engine error '80004005' 
    Unspecified error


    Objet Request error 'ASP 0104 : 80004005' Operation denied


  1. This is the permission issue in general.
  2. This is some misconfiguration in connection string


  1. Check if IIS user has permissions to write in the directory, where database file is located and also has permissions to read, write and modify in the system '%TEMP%' directory.
  2. check the ConnectionString property of ADODB.Connection is one of the following 4 variants

    1. 'CN.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=" & Server.MapPath ("path_under_httpdocs\access.mdb")'
    2. 'CN.ConnectionString = "Microsoft.ACE.OLEDB.12.0;Persist Security Info=False;DATA SOURCE=" & Server.MapPath ("path_under_httpdocs\access.mdb")'
    3. 'CN.ConnectionString = "Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Server.MapPath ("path_under_httpdocs\access.mdb")'
    4. 'CN.ConnectionString = "Driver={Microsoft Access Driver (*.mdb)};Uid=Admin;Pwd=;Dbq=" & Server.MapPath ("path_under_httpdocs\access.mdb")'
