Got it. I just confirmed that the firewall is off on both the XP and 7 systems. Is there any other subsystem to check?

Forgive me if I'm talking past you. The fact that the XML messages are not processed on Windows 7 is completely expected due to the UDP reassembly problem. What is confusing is why the same logic works on Windows XP. Your reply indicates that perhaps the raw socket on the XP system is getting the message after it has been reassembled by the system. That would indeed explain the behavior. Is there any documentation that you're aware of that indicates this possibility?

Right now, our system does not reassemble the UDP packets after collecting them via the raw socket. You're right. This is a bug in our system, a known shortcoming. It only rears its head when another system sends us 'large' messages, like these XML messages we're currently focused on. What I do not understand is why the messages are processed fine on Windows XP but not on Windows 7. The XML processor has no special logic to behave differently based on OS, so I would expect the XML processing to fail on both systems. But it seems to work on Windows XP. ???

@David Schwartz, a single send of the XML message winds up in two (in this case) IP packets.
