thank you Compton  computer browser service is working now and running, now I can view  the laptop and computer A files but still cannot access my own files in the network and the same thing with the laptop and computer B, When i typed in the CMD net view i saw computer B and the laptop about i didnt see computer A.

Same thing with the homegroup I can see computer A in it.

I really thank each everyone who helped I am getting closer to the fix The only problem is Computer A is not accessible in the Network but finally Computer A can access other devices on network.
Amr,
