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：

代码如下:

strcomputer = .

set objwmiservice = getobject(winmgmts:\\ & strcomputer & \root\wmi)

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：

代码如下:

strcomputer = .

set objwmiservice = getobject(winmgmts:\\ & strcomputer & \root\wmi)

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
