Powershell中的PC ping脚本

该脚本不断从导入CSV列1 ping PC主机名列表

第1列（主机名）第2列（用户）←手动更新字段

当脚本识别出3次失败的ping尝试时，它会通过/IP address/failed Pings向我们的电子邮件地址发送电子邮件，其中包含Time/Hostname/Owner（取自.csv文件）

这很好用。但是，当电脑重新联机时，它会发送另一封包含上述内容的电子邮件，但不会显示正确的所有者。有人能帮助将

$Back

所有者与相应的用户关联起来吗？就像它与最初的电子邮件回复一起工作一样。此时，无论第一封通知电子邮件是否正确，它都会在电子邮件的用户栏中显示任何内容或姓氏
