Configuring HTTP Error Responses in IIS 7
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Custom error messages let you provide a friendly or a more informative response by serving a file, executing a resource, or redirecting to a URL, when visitors to your site cannot access the content they requested.
By default, IIS serves error messages that are defined in files stored in the systemroot\Help\IisHelp\Common folder. You can create a custom error message for users and configure IIS to return this page whenever it encounters a specific HTTP error on your site.
You cannot customize the following HTTP error messages: 400, 403.9, 411, 414, 500, 500.11, 500.14, 500.15, 501, 503, and 505.
