Good evening to all those monitoring tonight. As a new user to the Windows operating system, I was wondering if it was possible to manually close or stealth the open ports of my computer? For example, ports 25, 110, 135, 1025. I am running the Home version of Windows XP and using ZoneAlarm as my firewall. Will I need a downloaded program - or is it possible to close ports using some aspect of Windows XP? Any reply, even if it is just a 'welcome to the site' - would be most welcome. Kindest regards xenestra.
