The fault will probably lie with one (or more) of the routing tables on the specific boxes. The NT box in the middle should be pretty much okay as the Network setup should add simple routes to point it at the right interface cards and you've already enabled IP Forwarding. A 'route print' and 'ipconfig /all' should show this to be the case. The routing table for the PC A appears okay as it can ping interface 1 which lies in the other IP subnet. The routing table for the CISCO is then probably at fault. It does not have a route in its table that tells it how to get to the subnet that interface 2 is in. This would prevent it from replying to pings from the PC A (via the NT box). I don't know how to configure CISCOs but it should be relatively straight forward to add such a route.
