No internet on Windows 7 virtual pc on Windows 7 with NAT configuration

I have installed Windows 7 on Microsoft virtual pc 2007 SP1 on Windows 7.I configured networking adapter to use Shared networking (NAT).But still I cannot access the internet from the virtual machine.

Note : Windows XP vms with the same settings (NAT) connects to the internet with no problem.

Executing ipconfig results:
