This problem may occur if the following conditions are true:
- You used the Database Interface Wizard in Microsoft Office FrontPage 2003 to create the database interface Web page.
- You set ASP.NET as the technology to use to connect to the database.
- The database is on a Microsoft Windows Server 2003-based Internet Information Server (IIS).
- A Microsoft Access Database (MDB) is used as the database source.
This problem occurs when a Microsoft Access database file is used as your database source because you must grant write access to both the default worker process identity and the authenticated user. By default, both Internet Information Server version 5.0 and Internet Information Server version 6.0 typically grant write access to both the default worker process identity and the authenticated user. However, when you use an MDB file as your database, these permissions must be granted by an administrator on the server that hosts the Web site.
