strComputer = "."

Set objWMIService = GetObject("winmgmts:" & strComputer & "rootwmi")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
("Select * from MSNdis_StatusMediaConnect")

Do While True
    Set strLatestEvent = colMonitoredEvents.NextEvent
    Wscript.Echo "A network connection has been made:"
    WScript.Echo strLatestEvent.InstanceName, Now
    Wscript.Echo
Loop

监视网络断开：

strComputer = "."

Set objWMIService = GetObject("winmgmts:" & strComputer & "rootwmi")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery("Select * from MSNdis_StatusMediaDisconnect")

Do While True
    Set strLatestEvent = colMonitoredEvents.NextEvent
    Wscript.Echo "A network connection has been lost:"
