Port Monitoring Using WMI

Question

Hi, I am working on a project, in which I have to monitor all the logical pots configured on the system, using WMI. If you can help me, i would be greatful to you. I am using System.Management NameSpace for WMI. I found PortConnector, PortReources classes in it, but both of them are not working for Logical Ports. thank you --Sanjay Tank
