I am on a Toshiba Satellite laptop running Windows Media Center Edition. I have the Apache server running but all of my ports are blocked by some unknown firewall. I've set up Zone Alarm to allow Apache into my "Trusted" zone and have even tried it with the Firewall shut down. There is no Windows Firewall (I removed SP2). How can I find out what's blocking all ports?
I am using Comcast as my ISP but they insist they are not blocking. I have also connected using Juno as the ISP with the same results.
