Dear Friends

I have install Win2012, Sql2012 and IIS8 on my local copmuter.
My problem is that when i set up new website on my IIS8 it will disconnect from local website and shown the message below in google chrome :
"This webpage is not available"
I should mention that website work fine but in some post back it will act like that, it seems very randomly and also my DNN6 package work fine on IIS7 And Win2008.

Kindly please help me get rid of this error !

Many Thanks In Advance

I know thats because of double DLL but i can not even erase one, i think this will case IIS8 to stop my website and then browser lost it !
Can it be possible?
Is there any way to avoid this error?

Many Thanks
