SYMPTOMS
When you visit a Web site that is hosted on Internet Information Services (IIS) 7.0 in a Web browser, you receive an error message that resembles the following:

Server Error in Application &quot; &quot;

HTTP Error 501.0 – Not Implemented

HRESULT: 0x00000000

Description of HRESULT

The page you are looking for cannot be displayed because a header value in the request does not match configuration settings.



CAUSE
This problem occurs because the client sends a request that contains the HTTP verb &quot;TRACE&quot;. However, the registry entry that is used to enable this HTTP verb is not configured on the server.



RESOLUTION
To enable the HTTP verb &quot;TRACE,&quot; follow these steps:  Click Start, click Run, type regedit, and then click OK. Locate and then right-click the following registry key:

 Point to New, click DWORD Value, type EnableTraceMethod, and then press ENTER. Double-click EnableTraceMethod. In the Value data box, type 1, and then click OK.
