Microsoft Windows SharePoint Services 3.0 includes a powerful new infrastructure for auditing user access to list items, and documents and pages. In Windows SharePoint Services, auditing is configured on a site collection-by-site collection basis. It just takes a few lines of code to fully enable the auditing for an entire site collection. When you do this, Windows SharePoint Services writes an audit entry to its audit log each time a user views or modifies a list item, document, or site page.
