Hi,<br><br>I have an enquire here. I'm running a ping plotter to several sites. For example, a tracert to yahoo is about19 hop. In the log file, it shows 18 hop results too. But after some time, the last hop will be missing. The ping plotter produces results till 17 hops only. This happens to many sites. Is there a way to solve this problem? And what's the cause of it?<br><br>
