For a start, two computers on the same network should have the same subnet mask. If two computers that are indeed on the same network have different subnet masks, there is a design problem.
Now, even if you look only at the last subnet mask - the least restrictive one - the computers are NOT on the same subnet mask. The subnet mask 255.255.0.0 indicates that the first two bytes (or the first 16 bits) of an IP address have to match, to be considered part of the same network. If you look at the IP addresses, this is not the case.
