Description
When a service will not connect, is the port closed, the firewall blocking, or the service simply not running? Testing one by one with telnet is slow and unclear. PortQryUI is Microsoft's graphical front end for the PortQry command-line tool: enter a target address and port, click once, and it tells you whether the port is LISTENING, NOT LISTENING or FILTERED.
It tests both TCP and UDP, which is handy for checking database, web and DNS connectivity without memorizing command-line flags. An official Microsoft utility, portable with no install.
Graphical interface: A GUI over the PortQry command line — fill in address and port and click, no flags to memorize.
TCP / UDP testing: Distinguishes LISTENING, NOT LISTENING and FILTERED so you know whether a port is closed or firewalled.
Connectivity triage: Pinpoints whether the problem is the port, the firewall, or the service itself.
Portable: A single official Microsoft utility that runs without installation.
