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?

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.

I've been *told* that a single hop timeout is not an issue. Especially
if it gets to the end of the route.

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.

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.
