About SOAP Fault messages
A SOAP Fault occurs when a request cannot be completed. Fault contains information identifying the source of the error or the component returning the error, the request, an error code, and a text description of the error.
In the following example, a request to download a file results in a SOAP Fault. The Description element contains a text error message and a reference to the requested file.
