SYMPTOMS
When you use the Microsoft Proxy Server service, a client request through the proxy may return the following error message:

Requested Header Not Found.

You may get the same error message when you request a Web page from an Internet Information Server (IIS) computer.



CAUSE
An authentication method under the WWW Service in the Internet Service Manager is not enabled, and the Proxy Server and IIS computers need credentials for the request.



RESOLUTION
Enable at least one of the authentication methods in the Internet Service Manager WWW service properties:

Basic (Clear Text)

-or-

Windows NT Challenge/Response

This will allow the Proxy Server or IIS computer to request credentials from the client web browser.
