Property Value

Type: System.String
A string specifying the name of an HTML file that contains error information. If the value is a null reference (Nothing in Visual Basic) or an empty string, or if the file that is referred to does not exist, Windows SharePoint Services returns a standard 404 response.

Windows SharePoint Services does not support the custom error pages that are typically used in IIS applications. There can only be one file per SharePoint Web application, which must be in HTML and cannot contain dynamic ASP.NET controls.
