Can you try to get the same report, from the same network connection, to the same host, but under windows 7? I believe on windows the command is "tracert", not "traceroute". And you'd need to run it from a CMD.EXE shell (you can get there from the start menu -> Run... -> "CMD", if my rusty windows memory is still relevant. --dkg
