IIS & Tomcat Installation Bottle Neck

[bsidu]

We are doing a proof of concept on a Single Server with our clients where we are trying to install Cognos Go Dashboard.

1. Cognos is set to work on IIS Webserver.

2. We installed Tomcat and configured it for the Go Dashboard Install.

3. The Service is up and running but the core issue is when we open Go Dashboard and try to drag a  report it doesnt execute. Everything looks fine.

I am wondering if its to do with two different web servers communication with each other.
