How come that the system process (pid 4) is listning on all :443 and :80? that means that only IIS can listen to those ports. not visualsvn for example (of course different IP's)
>netstat -aon
...
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4
TCP 0.0.0.0:443 0.0.0.0:0 LISTENING 4
...
i tried to disable the HTTPS traffic in rule and even disable the whole firewall, but it didn't help.
