Learn why Windows® Firewall is not working on the computer
What are the reasons behind the improper working of the Windows Firewall? How does the firewall useful to you?
Windows Firewall is a critical first line of defense to protect your system against various types of malicious software. If properly configured, this will help you to save the system from malicious attacks. Windows Firewall, which comes with Windows Vista, is turned on by default and protects the system as Windows starts. The Windows Firewall Control Panel is designed to be easy to use, with several configuration options and a simple interface. More advanced than the previous versions of Windows, the firewall in Windows Vista helps protect you by restricting other Operating System resources if they behave like a usual manner. For example, if a component of Windows that is intended to send network messages over a given port on your system tries to send messages by way of a different port due to an attack, firewall could prevent that message.
The following are some of the causes due to which the Windows Firewall doesn't work properly:
- ICS issues
- Software conflicts
- Improper settings
The Internet Connection Sharing service has a major role in the working of the Windows Firewall. Normally this service starts automatically and if this doesn't not happen, the firewall also will not work properly. To resolve this issue,start the ICS manually.
This is one of the common problems that might occur while using the Windows Firewall in the system. If the user installs any additional firewall software in the system, then these two will create conflicts and there will be continuous error messages. You could not use any of these software. To resolve this issue, disable any of the firewall in the system. The better option is to disable the additional software installed in the system. You could use the system restore option to resolve this issue. While restoring the system to any of the previous stage, the recently installed firewall software can be erased.
If the settings related to the Windows Firewall in the system are changed, then also the proper working of the firewall will be prevented. If the disable option of the firewall is turned on accidentally, the firewall wouldn't work. So, you need to check the settings of the firewall before adopting any other resolution methods.
