title: asp.net web service "page not found" after invoking method
body: <p>We have created a .NET 4 web service, which runs fine on a <strong>Windows 7 development</strong> pc. But now we have moved it to a <strong>Windows 2008 standard server</strong> which runs IIS. </p>
  
  <p>When we browse to the <strong>.asmx</strong> file we get the correct pages that show us the available web service methods, but when we try to invoke a method by using the provide test buttons, we get a "Page not found" error. </p>
  
  <p>Any suggestions on what setting / config line we should change? </p>
  
  <p>I guess, because we don't get a real (yellow background, red text) asp.net error, this has something to do with IIS not picking up the request when invoking a method?</p>
