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.
