What command do I use from the Internet to see if packets are getting through the firewall onto the Windows 2000 server on port 80? I'm trying to get OWA working and have been troubleshooting this for 2 hours now. I'm stumped. I've already gone through checking the IIS Lockdown tool, folder permissions, IIS virtual directory permissions and authentication, server certificate, firewall port forwarding, and I'm out of ideas. Thanks.
