ASP.NET Web Service ONLY returns Documentation Page for all calls
<p>A client has a ASP.NET web service on a shared server (hosted environment). You can go to the web service URL and view the documentation page (xxxxx/service.asmx?WSDL) and see all the methods. Using a tool such as SoapSonar you can execute any of the methods, but the response is always as if you sent (xxxxx/service.asmx) - in other words the web service documentation page. </p>

<p>Is this a medium trust environment? - I don't know, they don't know, don't ask</p>

<p>There are no errors returned or logged. 
This is on a Win2k3 server with 3.5 Framework installed and II6. The webservice was build with Visual Studio 2008 and works locally, just not in this environment.</p>

<p>The client has no access to the server, the third party server provider is trying but of limited experience using ASP.NET web services. </p>

<p>Any thoughts on what could cause this type of behavior? What to look for? </p>
