PortQry includes built-in shortcuts for complex services. You can use -p both to check both TCP and UDP. PortQryUI: The Graphical Interface

portqry -n 192.168.1.10 -e 80 (Checks if port 80 is open on the target IP.)

portqry -n 10.0.0.5 -r 135,139,445 -p tcp

: The port did not respond, likely because it is being blocked by a firewall on the target machine or network path. Key Features & Modes

PortQry has built-in knowledge of common services. If you query a known port (like SMTP on 25 or DNS on 53), it doesn't just check if the port is open; it actually interacts with the service to verify it is responding correctly (Banner Grabbing).

Portqry (Port Query) is a command-line utility developed by Microsoft for Windows operating systems. Designed to function as a more flexible and informative alternative to basic tools like Telnet and netstat , Portqry reports the status of TCP and UDP ports on local or remote machines. It is an essential tool for network administrators, security analysts, and support professionals to diagnose connectivity issues, firewall rules, and service availability without requiring a full client installation.
