Can I turn off impersonation just in a couple instances

I've created an application that, when uploaded to my server throws the following exceptions:

[Win32Exception (0x80004005): No credentials are available in the security package]
[AdomdConnectionException: Authentication failed.]

Here is my connection string:

public AdomdConnection conn = new AdomdConnection("Data Source=BTN-SQL1;Initial Catalog=BTNTurboAnalysisServices;Integrated Security=SSPI;SSPI=Kerberos;Persist Security Info=False;");

Its worth noting that BTN-SQL1 is on a different server to my web server and I'm also using Windows Authentication with Impersonation enabled.

Below is my stack trace:

[Win32Exception (0x80004005): No credentials are available in the security package]

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:
