Have you considered turning the firewall on and disabling the rules for the domain, public, and private sections? The default port for html access is 8443. For troubleshooting purposes I would just leave the firewall on but disable the rules.
Click Start, click All Programs, click Administrative Tools, and then click Windows Firewall with Advanced Security.
In the navigation pane, right-click Windows Firewall with Advanced Security on Local Computer, and then click Properties.
On each of the Domain Profile, Private Profile, and Public Profile tabs, change the Firewall state option to Off (not recommended).
Click OK to save your changes.
Or just create a rule to allow everything.
