C:\scripts>type monitor.cmd
@echo off
setlocal
if {%1}=={} goto noparms
if {%2}=={} goto noparms

REM Please copy portqry.exe to the same folder with monitor.cmd.
portqry -n %1 -e %2 -q

IF %ERRORLEVEL% EQU 1 goto down
IF %ERRORLEVEL% EQU 0 goto up

:noparms
echo Usage: monitor.cmd ServerIP PortNumber
goto end

:up
echo The %2 port is listening on %1...
goto end

:down
echo The %2 port is not listening on %1...
goto end

:end

执行该脚本的结果：
C:\scripts>monitor.cmd
Usage: monitor.cmd ServerIP PortNumber

C:\scripts>monitor.cmd bbs.nsfocus.com 80
The 80 port is listening on bbs.nsfocus.com...

C:\scripts>monitor.cmd bbs.nsfocus.com 79
The 79 port is not listening on bbs.nsfocus.com...

你可以根据你自己的需要对这个脚本进行改动，Hope it helps...

附上PortQry的用法：
PortQry Usage:
PortQry.exe -n server [-p protocol] [-e || -r || -o endpoint(s)]
　　　　[-l logfile] [-s] [-q]

Where:
　　　　-n [server] IP address or name of server to query
　　　　-p [protocol] TCP or UDP or BOTH (default is TCP)
　　　　-e [endpoint] single port to query (valid range: 1-65535)
　　　　-r [end point range] range of ports to query (start:end)
　　　　-o [end point order] range of ports to query in an order (x,y,z)
　　　　-l [logfile] name of log file to create
　　　　-s ''slow link delay'' waits longer for UDP replies from remote systems
　　　　-q ''quiet'' operation runs with no output
　　　　　 returns 0 if port is listening
　　　　　 returns 1 if port is not listening
　　　　　 returns 2 if port is listening or filtered

Notes:
　　　　This version runs on Windows 2000 and Windows XP
　　　　Defaults: TCP, port 80, no log file, slow link delay off
　　　　Hit Ctrl-c to terminate prematurely
