Can I turn off impersonation just in a couple instances

I’ve created an application that, when uploaded to my server throws an exception. It works fine locally but the moment I upload it to my server I get the following error:

System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Here is my connection string:

AdomdConnection conn = new AdomdConnection("Data Source=BTN-SQL1;Initial Catalog=BTNTurboAnalysisServices;");

Its worth noting that BTN-SQL1 is on a different server to my web server, could that be causing a problem? I’m also using Windows Authentication.

Below is my stack trace:

Any help would be appreciated, thanks!

I’ve managed to solve the problem. Basically I just disabled impersonation for the specific methods that were causing the problem by using the solution found here:
