IIS cannot read or write to a database (ACCESS) problem
The main reason is that the database data cannot be updated, such as no write permission, etc. generally have the following two points:
1. Your database is in Access format, and your database file has the attribute "read Only".
2, your database for access format, your Web site program and database is placed on the NTFS file format disk.
Solution:
1, in your database file property bar will be "read-only" before the "√" point off.
2. Check the Windows file System (NTFS) permissions for the folder where the database files reside. If so, open My Computer, right-click the file, change the property in the security to IUSR_ your computer name this user plus write modify permissions. User name is not necessarily this, in IIS Check Web site Properties-> Directory Security-> authentication and access Control point "edit", which is selected "Enable anonymous access" and that "use the following Windows user account for anonymous access" is the account to which you want to add permissions.
WinXP you need to cancel the default simple sharing mode to set NTFS directory permissions. Open My Computer, click tools → folder Options, select the View tab in the Open dialog box, and empty the check box before use simple sharing (recommended).
