Testing Service Connectivity with PortQry
If you ask a bunch of systems administrators what tools do they use when troubleshooting remote services and ports, one of the top answers would definitely be the Telnet client! Windows 7 includes a Telnet Client but it is not installed by default. However, a tool that is more flexible and powerful than Telnet Client is PortQry. This tool has been around since Windows 2000 and version 2 has more features, you can download PortqryV2.exe from Microsoft’s Download Center as it is not included with Windows 7.
