tracert times out
I want to do a tracert on comcast.net (my ISP) and it always times out, yet
I can get e-mail and see newsgroups. What does it mean then and what to do to do a tracert? |

Note: This is not a hardware issue. microsoft.public.windowsxp.hardware was removed from my reply. Have you tried upping the timeout? It's a command-line parameter to 'tracert'. If you are using a firewall, did it allow both TCP *and* UDP traffic for that application? Some firewall are screwed up as delivered at install-time by blocking ALL ping requests, including the return from tracert (Comodo v3 was like that and I don't know if they fixed it). |

tracert times out
I use TREND MICRO Pro. Ping always times out. Time out is 2 seconds.
I do not know where to increase the time out period. When I go into the TREND Micro database and search for "ping" or "timeout" it finds nothing. "VanguardLH" wrote in message . ..

tracert times out
So when you type "tracert www.comcast.net" into a command prompt window it
times out, I've just tried it and it's ok in 9 hops. Neil "Ritter 197" wrote in message ... I want to do a tracert on comcast.net (my ISP) and it always times out, yet I can get e-mail and see newsgroups. What does it mean then and what to do to do a tracert? |

ALL hops timed out. 30 of them. There is some background information on traceroute here. http://en.wikipedia.org/wiki/Tracert What if an important port number was blocked by Comcast for their own customers ? That might mean the difference between a Comcast customer running the test, and those of us outside the Comcast network running the test. I didn't have any problem running traceroute here, against either www.comcast.net or just comcast.net, and I'm outside Comcast. Maybe you can make enough sense out of that Wikipedia article, to come up with another test. Perhaps your own firewall is the reason the test failed. Comcast had some issues just recently, and may have made adjustments to their network in an effort to figure out the problem. And in any case, like any ISP, if you phone up and ask them a question, you'll get that "we're innocent" routine. Tech support will never admit to any filtering, even if it is for good and logical reasons. http://www.dailytech.com/article.aspx?newsid=11925 Paul "Big Al" wrote in message news:nXG0k.1093$jX.28@trnddc04...

How about firewall interference?

Most of the Comcast servers will not respond to a tracert probe. It's normal and not under your control. Many ISPs to it to limit traffic during high traffic times and/or to prevent probes from internet static. Nothing you can do about it. |

It is possible that one of the routers (probably the one you connect through) has been set to not reply to Pings. Tracert uses ICMP pings to work it way through, and if pings are being blocked it will not work, and timeout.

Tracert and TrendMicro Firewall
I've run into the same issue with tracert and the TrendMicro Firewall. If your Firewall is set to any level above MINIMUM, tracert doesn't work to any IP. Set your firewall to minimum and it will probably work.

UPDATE
I was trying to get ping and tracert to work with Trend Micro's Firewall set to Maximum and discovered the fix.
In the advanced settings of the Firewall, add both programs as allowed. Then go to the Network Control Protocol window and add two rules. One to allow Outgoing ICMP (this opened up PING) and another to allow Incoming ICMP (this fixed TRACERT). I still show up as fully stealthed even in the DMZ on my router with Trend's firewall at low. YMMV |
