How to reset Windows Firewall settings in Windows XP SP2

There are situations where-in you need to reset your Windows Firewall settings, after removing a Trojan etc. Resetting the Windows Firewall sets the configuration to factory defaults by removing all the programs / port / exceptions settings.

To reset the Windows Firewall to the factory default state, try this:

* Type firewall.cpl in Start, Run dialog.
* Click the Advanced tab.
* Click the Restore Defaults button.
* Click Yes to continue when you see this dialog

Restoring the default settings will delete all settings of Windows Firewall that you have made since Windows was installed. This may cause some programs to stop working.

Do you want to continue?

The Windows Firewall is now turned ON, and set to factory default state.

Alternately, you can use the NETSH command-line to accomplish this:

Open a Command Prompt window and type NETSH FIREWALL RESET

This command resets firewall configuration to default. This provides the same functionality as the Restore Defaults button in the Windows Firewall interface.
