Hi all,

I have a Silverlight application, that makes use of it's web.config file to get it's conneciton string. The connection string has be encrypted with RSA utility that runs on the same machine. I receive the following exception each time I run the Silerlight application. Strange thing is that it works with another Silverlight application that runs of the same PC :confused:

I used to get the same error when Web.config was encrypted (for asp.net applications also). I used to run the following commands to resolve it. Not sure whether it will help you, but please give a try.

VB

aspnet_regiis -pc "NetFrameworkConfigurationKey" -exp
aspnet_regiis -pa "NetFrameworkConfigurationKey" "ASPNET"
aspnet_regiis -pa "NetFrameworkConfigurationKey" "NETWORK SERVICE"
aspnet_regiis -pa "NetFrameworkConfigurationKey" "NT AUTHORITY\NETWORK SERVICE"

I fixed the problem by using the following steps:

1. First of all, I was working on Windows Server 2008
2. Open IIS
3. Navigate to the web site that is causing the problem
4. Under Security within the Home section of the web site, click on the 5. Authentication icon
6. Disable ASP.NET impersonation
