I'm losing my nerves with an error that I never have encountered before: I set up a simple SOAP web service, that runs on .net 4, which receives a string as the input and returns a XMLDocument.
When testing the service in the developer environment, i.e. the ASP.NET development server, everything works fine, however when I put the WS on the IIS7 server, the server refuses to process the request and returns a Error 500, stating: "Server was unable to process request - The data is invalid."
I test the WS from a client that is located in the same network, but different machine. The SOAP request that is sent from the client is modeled exactly the same as demanded by the WS. The request is without doubt correct, as I manage to properly call the WS from a local client, communicating with "localhost".
Are there perhaps some extra settings I need to configure on the IIS7?
Cheers, Alois
