I'm using the "Trace in PingPlotter" option in MultiPing, so I guess it would be the same target (IP-address). The default packet type is also chosen (I haven't really changed anything in the two programs), so it should be the same packet type for both. Also the timeout is set to 9999 ms.

Trace interval is set to 5 seconds and samples to include are 10. The # of times to trace is set to unlimited in PingPlotter. Is there a setting for this option in MultiPing?

I can try and ping the final destination only. Is that the same as "Send data to PingPlotter" (just wondering)? Because that showed the same errors yesterday as the ones in MultiPing. However, the problem is that my ISP want a logfile with all hops and times.

But I'll to monitor again today and get back to you! Again, thanks for this great support!
