While I'm not necessarily opposed to dropping the success check as you propose, I think there may be a better improvement, too. What results do you get if you apply this patch?

This changes the request from a version 4 to a version 2 packet, which may be more widely supported (version 3 appears to be the consensus, and each version is backwards-compatible with previous ones except for version 1). If this solves your issue, I'd be inclined to just limit the change to this for now. Though your idea does bring to mind the fact that most UDP NSE scripts do not attempt to retransmit packets, which means that network congestion could result in lost results.
Hello Dan, Unfortunately these specific targets do not respond to NTPv2 client requests either. They do respond to the control requests. As far as I can tell they are Cisco 2911 routers but I know nothing about their specific software version and/or configuration.
