a Security tab.

To assign the IUSR account full permissions, select Full Control from the Type Of Access menu and click OK.

Troubleshooting Microsoft error messages
These Microsoft error messages can occur when you request a dynamic page from the server if you use Internet
Information Server (IIS) with a Microsoft database system such as Access or SQL Server.
Note: Adobe does not provide technical support for third-party software such as Microsoft Windows, and IIS. If this
information does not fix your problem, please contact Microsoft technical support or visit the Microsoft support website at
.
For more information on 80004005 errors, see “INFO: Troubleshooting Guide for 80004005 Errors in Active Server
Pages and Microsoft Data Access Components (Q306518),” on the Microsoft website at
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q306518.
[Reference]80004005—Data source name not found and no default driver specified]
This error occurs when you attempt to view a dynamic page in a web browser or in Live view. The error message may
vary depending on your database and web server. Other variations of the error message include:
• 80004005—Driver's SQLSetConnectAttr failed
• 80004005—General error unable to open registry key 'DriverId'
Here are possible causes and solutions:
• The page can’t find the DSN. Make sure a DSN has been created on both the web server and on the local machine.
• The DSN might have been set up as a user DSN, not as a system DSN. Delete the user DSN and create a system DSN
to replace it.
Note: If you don’t delete the user DSN, the duplicate DSN names produce a new ODBC error.
