i am configuring Apps environment on SharePoint 2013...although I have followed several articles explaining the  configuration but I am not been to set it up...I tried both methods i.e. by creating new domain and by creating child domain. Below is the screen shot that displays when I ping to my new and child domain...

I am looking forward for some tips with tons of thanks...
