We have created a .NET 4 web service, which runs fine on a Windows 7 development pc. But now we have moved it to a Windows 2008 standard server which runs IIS.
When we browse to the .asmx 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.
Any suggestions on what setting / config line we should change?
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?
It turns out that the friendly error message option in Internet Explorer kept us busy for a while. After turning of this developer-unfriendly-feature, we were able to move on with the real problem.
