How to make custom error messages?

1. In IIS Manager, expand the local computer; expand the Web Sites folder, right click on an individual Web site folder and then click Properties.

2. Click on the Custom Errors tab.

3. In the Error messages for HTTP errors listing, you can modify HTTP error that needs to change, and then click Edit. [These errors are not customizable: 400, 403.9, 411, 414, 500, 500.11, 500.14, 500.15, 501, 503, and 505.]

4. You have multiple options for custom error pages, either File to display a custom error file or URL to forward the error request. [For an .asp page, select URL, because do not select URL, danger of returning .asp source code to the visitor.]

5. For File option, provide the path to the file with Browse. Custom error messages are available under the systemroot\Help\IisHelp\Common folder. The file names are same as HTTP error numbers; for example, 404 to 404.htm.

If you enable a custom error page that provides substatus information weaken the security of IIS. So do it temporarily or only for troubleshooting purposes.
