Problem: Cannot access Web application

1. Make sure IIS is not running.
2. Ensure that there is no firewall software, including the "Internet Connection Firewall" (ICF) that is bundled with Windows 2003. You can check if ICF is enabled:
   1. Navigate to Control Panel > Network Connections.
   2. Right-click on the Ethernet adapter (Local Area Connection).
   3. Select Properties.
   4. Click the Advanced Tab.
3. If the Protect my computer... option is enabled, uncheck it and apply the changes.
