VBS 批量Ping的项目实现

用VBS实现一个批量Ping的工具，在实际运维场景中非常实用。下面这段脚本不仅支持循环检测、断线计数，还能在连续失败达到阈值时自动发送邮件通知——相当于一个轻量级的网络监控看门狗。整体结构清晰，适合直接拿去改改就能用。

'判断当前VBS脚本是否由CScript执行
If InStr(LCase(WScript.FullName), "cscript.exe") = 0 Then
    '若不是由CScript执行，则使用CScript重新执行当前脚本
    Set objShell = CreateObject("Shell.Application") 
    objShell.ShellExecute "cscript.exe", """" & WScript.ScriptFullName & """", , , 1
    WScript.Quit    '退出当前程序
End If

整个脚本的核心逻辑很直接：通过WMI调用Win32_PingStatus一次性查询多个地址，然后根据StatusCode判断连通性。连续断线10次就触发邮件告警，同时日志和控制台都会同步输出。邮件部分用的是CDO，配好QQ邮箱的SMTP参数就能直接跑。需要注意：运行环境必须是CScript（默认的WScript不支持标准输出），脚本开头已经做了自动切换处理。
