CAUSE

This issue occurs if the user account under which the application runs has insufficient permissions.

If code is executed from a custom Windows-based application or from a custom console application, the code path does not use the Web context that is hosted by the Microsoft Internet Information Services (IIS) application pool. Therefore, specific user permissions are required in SharePoint Server 2007 and in the back-end data source.

RESOLUTION

To resolve this issue, make sure that the following conditions are true for the user account under which the application runs:

The user is a server farm administrator.
The user has Read and Write permissions on the content database.
The user is a site collection administrator.
The user has permissions to access the Windows SharePoint Services site or the SharePoint Server 2007 site through which the code iterates.
