Can ping the machine on the web, but cannot access the web server

[Kenan]

I'm trying to access the friend's computer using IE. He has Apache
Tomcat installed. I can ping his machine, but I can't see the Tomcat
root. He can type in his browser something like http://localhost:8080
and he sees the root, so Tomcat is running for sure. ICF is disabled
and we also uninstalled Norton AV. What could be the reason that I
can't access the machine using http?

It sounds like his web server is running on port 8080.
Have you tried using http://<hisIPaddress>:8080 to go to
port 8080?

If that doesn't work, it's possible his ISP is blocking
that port.

Yes, I have tried http://<hisIPaddress>:8080, it does not work. I
tried ports 81, 90 also, no luck. I guess ISP (Cox Cable) is not
blocking ports.
I don't know what else to try.

You said

But, you've missed several more steps, at least these:

#1)
He should verify it is running bound to the external address
that you're trying:
http://<hisIPaddress>:8080
(have him try that from the machine itself)

#2)
Was there anything in the logs around the time you tried to
connect from your client ?
