Take a few minutes to customize your Internet Information Server (IIS) site by specifying a page (other than the default) to handle erroneous page requests. The standard response page looks like this:

 HTTP Error 404404 Not FoundThe Web server cannot find the file or script you asked for. Please check the URL to ensure that the path is correct. Please contact the server's administrator if this problem persists.

It is simple in the IIS admin program to specify a different page. Go into your Default Web Site properties, and select the Custom Errors tab. You will see a list of error codes and their associated pages. Replace the associated page with one that looks more consistent with your site, and give your users a more descriptive message or show the site map. This technique helps your site look more professional.
