Question : Problem with SOAP application on IIS  "502 - Web server received an invalid response while acting as a gateway or proxy server"

Update: here's the problem with no solution on Embarcadero's Quality Central: http://qc.embarcadero.com/wc/qcmain.aspx?d=42695
I'm busy trying to learn SOAP, and if I build and deploy one of the demo applications it works, but if I try access any of my soap server applications in a browser, I just get this error generated by IIS:

"502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server."

It's very strange that the client application can make a request to my SOAP server applications, but with my browser I just get an error, and in Delphi if I use the WSDL Import Utility I get the same kind of error:

Unable to load WSDL File/Location: http://196.xxx.xxx.xx/scripts/DBAttachServer.exe/wsdl/IDBAttachments.  Error [Bad Gateway (502) - 'http://196.xxx.xxx.xx/scripts/DBAttachServer.exe/wsdl/IDBAttachments'].
