The easiest way to brand your Web services and associate all Web services with your company s image is to modify the template page used to render the Service help pages for all Web services. By default, this page is named DefaultWsdlHelpGenerator.aspx and it is located in the same directory as your Machine.config file. You can open this file with a text editor and insert HTML after the body element. The HTML inserted here is then rendered along with the Service help page for every Web service accessed on that machine.

Use regular expressions to search for the phrase boot.ini in the filename This will work, but it is risky because the attacker can find another way to identify the file.
