Monitoring Opened TCP/IP
CurrPorts is network monitoring software that displays the list of all currently opened TCP/IP and UDP ports on your local computer. For each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it.

PRTG 網路系統監控軟體
PRTG是一套由德國Paessler公司所開發的Windows應用軟體，主要應用於系統網路的監控。
提供免費版下載，可監控100 Sensors，對一般中小型企業應該很夠用了。
多力哥常用來監控主機的網路流量、CPU、記憶體、硬碟容量的使用情形
安裝很容易，windows作業系統記得要開啟SNMP服務，並允許PRTG接受SNMP封包
執行PRTG的主機建議找最穩定的，這樣才能有效監控其他主機^^
當主機發生問題時可以設定郵件通知，你可以進入PRTG網頁介面看看詳細內容
他們也提供多國語言包喔！
