IP same subnet not pinging

This usually indicates a host configuration issue. A host firewall is the most common issue I see. For instance Windows Server 2008 R2 will, by default, not respond to ping (icmp echo request) due to Windows Firewall settings.

To troubleshoot I do a packet capture on the destination system (after verifying subnet mask etc.) to see if the incoming packets are seen.
