If a visitor's attempt to view a page on your website fails, the server will generate and send an error page, which is displayed in the visitor's browser. These default error pages are not terribly attractive—consisting of an error code and a cryptic description of what went wrong in unstyled HTML—but they are easy to replace with custom error handlers. Since an error handler can be any page you wish, it is easy to base an error handler on the same template you used to build your website (e.g. same navigation bar, same text style, etc.).
Note: If you use any Error Code handlers, FrontPage extensions will not work correctly. If you wish to use FrontPage extensions, please install FrontPage first, and then use FrontPage to install the Error Handler(s) of your choice.Click the in your Control Panel.
