WCF: The message could not be processed:

I have created a WCF service which I am hosting as an application under my site on an IIS7. It is running on one server a开发者_高级运维nd now I am trying to make it run on a second server. When I call the service I get the following error:

The message could not be processed. This is most likely because the action \u0027http://tempuri.org/IMyService/myMethod\u0027 is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings.

I have set the security in the wsHttpBinding to None, so in my naive mind I conclude that it is not a security problem.

What might I do wrong and how should I proceed to determine what the exact problem is?

Maybe you have the same channel URI. Change it for second server. You can't use same URI for boths.
