监视网络连接与断开，特殊情况下可能有点用，两个VBS脚本均来自微软官网
监视网络连接：
复制代码 代码如下:
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：
复制代码 代码如下:
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:"
WScript.Echo strLatestEvent.InstanceName, Now
Loop
