MTM

Hi,

I am a beginner to MTM. I am trying to configure Test controller with TFS. Here i am using Visual studio 2012 with Microsoft update 4, TFS, Microsoft Test Manager.
1) I successfully checked in the code into my TFS and integrated MTM with TFS.
2) I added CodedUI and successfully Checked in.
3) Successfully assigned script to test-case.
4) Now i am trying to create a lab environment. But it is asking me to config a Test Controller.


Here i am trying to configure the Test Controller. It showing that the controller is not Responding. It at all it started configuring it is taking more time to configure and at TFS Login it is showing that TFS login is failed and lab services login is failed.

Can any one please suggest me how to over come this problem.
