Hi,

This is a commen error message in Silverlight application. The first thing I would suggest is to explicitly specify binding configuration in web.config. In .NET 4 Visual Studio does not generate binding configuration for WCF service anymore and uses implict configurations, which may vary in different environments. Secondly, if you're using HTTP binding, you can use Fiddler to see the HTTP response from server, which can tell you what the problem is. Please let me know what you find in Fiddler log so that we can do further troubleshooting steps.
