Hi.<br><br>It *sounds* like you may be tracing to destinations that don't respond to ICMP echo requests. Give me some examples of IP/Names that are causing you problems and I can verify this.<br><br>Does Ping Plotter show the round trip time after the last hop? It only shows this on complete traces (where the destination was reached) - and its absense would be another clue that you're not reaching the final destination.<br><br>The real decider on this, though, is to compare the IP address you specified with the last IP address in the route. If these match, and you're not getting a timeline graph, then it's possible they've been specifically supressed for that hop. Just right-click on the hop and turn on the timeline graph.<br><br>These are just some hints and clues to get you going. Without seeing any details, it's hard to diagnose exactly. If this doesn't help, let me know some of the IPs that are causing problems and I'll try troubleshooting from here.<br><br>
