🔥 RDP or an Application Blocked? Don't Disable Windows Firewall!
Use netsh advfirewall to inspect firewall profiles, review rules, and safely troubleshoot blocked network traffic.
💻 Useful Commands:
netsh advfirewall show allprofiles → Check firewall status
netsh advfirewall firewall show rule name=all → View firewall rules
netsh advfirewall firewall show rule name=all | findstr 3389 → Search for RDP rules
Test-NetConnection -Port 3389 → Verify port connectivity
🔄 Troubleshooting Flow:
Check Firewall → Check Rules → Identify Required Port → Allow Only Required Traffic → Test Connection → Verify
💡 Pro Tip: Keep the firewall enabled and use least-privilege rules. Don't create broad “Allow Any” rules just to make a connection work.
