我正在尝试为文本文件中提到的服务器列表生成服务器状态HTML报告。我的一些服务器位于不同的域中，因此它给了我错误。

错误：

Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At C:\Users\raj.negi.RESONATE\Desktop\WinServ-Status.ps1:143 char:32

    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
    + FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

它适用于运行脚本的同一域中的服务器。 enter image description here

我能够成功ping通其他域服务器。
