This issue occurs if the port that Microsoft Internet Information Services (IIS) uses is blocked by a firewall. By default, Windows Firewall is enabled in Windows XP SP2.
Note Windows Firewall was previously named Internet Connection Firewall.
To work around this issue, open the TCP port that is used by IIS. For example, if IIS is configured to use the default port 80, open port 80. To do this, follow these steps.
