Beside all that i dont know how sam spade was trying to figure out the prob .
but when it found the first . let me show you the out put.
1 192.168.0.1 150ms 130ms 170ms TTL: 0 (ds1.some.net bogus rDNS: host not found [authoritative])
2 192.168.0.130 150ms 231ms 140ms TTL: 0 (com.net ok)
3 192.168.0.130 201ms * * TTL: 0 (ok)
4 192.168.0.130 * 160ms 230ms TTL: 0 ( ok)
5 No Response * * *
6 192.168.0.130 160ms * * TTL: 0 ( ok)
7 No Response * * *
8 192.168.0.130 * 140ms 151ms TTL: 0 (ok)
9 192.168.0.130 160ms * * TTL: 0 ( ok)
10 No Response * * *
11 192.168.0.130 240ms * * TTL: 0 ( ok)
.................................................................................
29 192.168.0.130 220ms 140ms * TTL: 0 ( ok)

this was the output i have changed the ips and hostnames. suppose i have 192.168.0.1 is my default gateway and 192.168.0.130 is the pc some time with response and some time dont and replying with unreachable destinations it will show the tracert's output too.
c:\tracert www.yahoo.com

1 451 ms 470 ms 481 ms ds1.some.net. [192.168.0.1]
2 431 ms 461 ms 360 ms [192.168.0.130]
3 net-.some.net [192.168.0.130] reports: Destination net unreachable.
