  • 0

I have an application that is built using ASP.NET, with an embedded Silverlight Object that communicates with a WCF back end. It is set up like so:

Server 1: Hosts ASP.NET Website on IIS7

Server 2: Hosts WCF Application on IIS7

My Machine will try to access Server 1 over the internet to log in to the website. Server 1 will the authenticate the user using the WCF Web Service over our internal network on Server 2. I can do this but when it loads the silverlight object it crashes, complaining about CrossDomain/ClientAccessPolicy failure. So to be sure I put those two files on every folder in the inetpub/wwwroot on both Server 1 and 2, just to be sure. But I am still getting the same error.

When I run the application from Server 1, it can connect to the site through its local network IP and it all works, it also works when I run the ASP.NET application from Visual Studio 2010 on my own machine, with the web service references pointing to Server 2.

I am almost at my wits end, there have been so many red herrings that I have tried and none have worked. I am not even sure if it is Silverlight/WCF or the IIS configuration on each server that is breaking it.

If anyone can help me shed some light on this I would greatly appreciate it.

Thanks,
Stuart.

    I found the issue to my problem. I was not realising that the Silverlight application was trying to access a web service that was restricted by firewalls, so I had to create another web service that would re-route through the website and to the original web service.

    What a bloomin’ pain!
