Apache windows 98 and Mediacom

I have installed apache webserver on my windows 98 machine. Note: This is just for playing and not a production machine.
The problem I am having is that it installed great, no errors, and I start apache and type
htt://localhost/ and my default webpage displays fine.
But if anyone trys to connect to my website: They get nothing, server not found....
I had them try
http://my ip/Index.html
and
http://my computer Name.mchsi.com/Index.html
The second example shows that I am on the new mediacom network(Old Att broadband using excite before).
Any ideas, I did install the apache 1.3.23 version for windows.
Thanks,
Dean

Is your ISP blocking ports? (to prevent you from doing exactly what you're trying to do?)

ATT has probably firewalled you. Most consumer broadband account licenses don't allow you to act as a host, but until "Code Red" ran amok on the Internet lat year it was a legal issue not a technical one. After "Code Red" they reconfigured their firewalls to block inbound tcp/ip port 80 and other potential infection points.

Is there a way to reconfigure Apache to run an another port? What other options do I have? ANy?

You are probably out of luck. Most ISPs take the 'block everything, except what is needed' approach to security (or at least, now they do).

One thing you *could* try is going to grc.com and seeing what ports his site manages to sniff out on your PC. Most of them are reserved for something else of course, but this would tell you at least something about your ISP's security/port blocking policies. Failing that, just ask them.

Well everyone, I finally got apache to work. I had to uninstall apache, and then reinstall to my c:\ directory, previously I went to the default directory apache recommends c:\Program Files\Apache Group\. I don't know if installing it to just c:\ helped or just the reinstall. Thankyou everyone for your help.
