Windows Firewall Troubleshooter–Automatically Diagnose and Fix Issues with Windows Firewall


There is not much reason why you need to mess around with Window’s Firewall setting. The most common case when you would interact with Firewall settings is granting an application access to any network activity. For example, the first time launch Chrome, Windows Security would prompt you for an alert to ask for the permission to grant Google Chrome to communicate to those networks.


If your computer suffered some serious issues related to network, for example, unable to login to your computer with Active Directory, unable to initiate Remote Desktop even when all the settings are configured correctly. Any abnormal network related behavior could be a result of bad Windows Firewall setting.
