Smoke is not appearing in Cycles render

Hi everyone,
I am stuck in a unique problem. I created a smoke as per a detailed tutorial. It is appearing in my view port, but it is not appearing during rendering(Cycles). I have attached both the snapshots and workfile. I am using Blender 2.74

The interesting thing is that, I even downloaded a completed smoke blender file from internet. Even that is not giving any smoke when I render in my system. Please help me out.

Thanks and Regards Sabin!

Is the domain object set to not render in the outliner or ray panel in object properties? Or is the smoke set to not display?
