IIS : You can ping the box but can't connect to IIS

Had the problem recently.

Laptop all running smoothly - could ping it no problem and connect to it via \\name.

But no way could I http to a website on the laptop.

Did the "ipconfig /flushdns" dance - no joy.

Double-checked all the IIS settings.

Had a chat with Mr. Google and found a suggestion to:

telnet "IP address" 80

This tests if port 80 is open.

No joy - aha - so it's not IIS per se - it's the TCP/IP traffic on port 80.

Run up Windows Firewall. Yup - HTTP traffic on WWW was disabled for port 80. Allowed that - bingo - all A-OK.
