W7 X-64 and IIS. No connection from LAN

Hi jimbo45 -

Could you give more details about your solution?

It appears that I'm having the same problem you originally described but I'll type it out just to be sure

I have two machines running windows 7 rc x64 7100 - they can both ping/remote desktop/share files but neither machine can browse websites hosted on the default site on port 80 of the other machine.

I've just completely removed all iis-related components, rebooted, re-installed everything needed* yet still the other machine cannot see the site.

I've used fiddler to check the request which is leaving the other computer. It looks fine, a standard GET. On the website host computer, I can see that no connection arrives (I'm using a software which has built-in connection-monitoring features and see no connection to port 80 either blocked or allowed). It as though the connection goes missing somewhere between the two computers.

I notice that SYSTEM is listening to port 80 using TCPv6 and wonder if this is somehow related to the issue as I have extremely limited knowledge of TCPv6. For IPv4, I have static IPs for all computers on the network but the IPv6 are all dynamically assigned by the same router/gateway.

I've attempted to disable IPv6 using the registry poke described here: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista - but IIS (SYSTEM) still listens on TCPv6

Generally, I have windows firewall completely disabled for the home and public profiles and my other software firewall enabled. I have also tried this with all firewalls disabled and my router's modem disconnected from the 'net - still with no success.

I have no clue what is happening... Any ideas?

Have you checked the sites bindings to the IP address and port in IIS manager?

Hi - thanks for reply. Binding is the default:
type:http, host name:<blank>, port:80, ip address: *, binding information: <blank>


Sorry for delay - I hadn't enabled 'instant email notification'...


Edit: it turns out (i believe) that my ipv6 addresses are auto-assigned, i.e. fe80...

Edit2: ...and I can't ping using the ipv6 address ! - surely this is related....

Hi - Would you please let know the possible solution.... I am facing the same problem and trying for a fix...

Just wanted to bump this because I just ran into the issue with two coworkers machines. We were trying to get IE6 to connect to their local IIS sites from within a Windows Virtual PC VM.

While troubleshooting, I couldn't even telnet to port 80 on their machines from my own machine. I even disabled windows firewall service.

The solution ended up being having to explicitly enable the INBOUND rule for World Wide Web services in the Windows Firewall with Advanced Security console. I guess even when disabling the firewall, some rules are still on...

Start -> Firewall
Windows Firewall with Advanced Security
Inbound Rules
scroll to the bottom, right-click on the World Wide Web Services [HTTP Traffic In] rule and click enable.

Hope this helps others!

thanks j2theb, I was running into the same problem and your solution fixed it...
