port blocking

About this tag
Port blocking in Windows involves configuring the Windows Firewall or third-party tools like Comodo to restrict network traffic on specific ports for security or access control. Common scenarios include blocking internet ports 80, 443, and 8443 for certain users while allowing LAN access, troubleshooting Remote Desktop connectivity issues when ports like 3389 are blocked by routers or firewalls, and managing system services that listen on ports such as 139 even when related services are disabled. Discussions cover Windows 7, 8.1, and Server 2012, with emphasis on firewall rules, port changes, and service configurations to achieve desired network behavior.
