Question

我正在尝试编写一个脚本，它将为我提供一个列出服务器名称和子网掩码的.csv，但仅限于子网掩码等于255.255.255.0（/ 24）。理想情况下，我希望以电子表格格式提供此功能，其中服务器位于一列中，而SM位于下一列中。我想我今天已经在这个问题上工作了太长时间，而且我正在使用＆＃34; scripter＆amp;＃34;。如果我能回答任何其他问题，请告诉我，这是我到目前为止的代码。我不是在找人自动为我解决这个问题！

我正在努力学习，我只是陷入困境，不知道为什么剧本是＆＃34;挂＆＃34;在某一点上，当它遇到它将查询网络适配器（Get-WmiObject）的部分时，它似乎挂起。感谢您帮助我指出正确的方向。

如果Get-WmiObject命令挂起/失败，请隔离失败的服务器。你能在循环中立即添加Write-Verbose吗？只是为了看看循环在服务器列表中走了多远，以及每次都挂在同一个服务器上。

该功能还存在一些支架问题：

New-Object -TypeName PSCustomObject -Property @{
  Server = $serverName
  SubnetMask = $SubnetMask |
    Export-Csv C:\Temp\PSPSubnetMask.csv -Append
}

应该是：

New-Object -TypeName PSCustomObject -Property @{
  Server = $serverName
  SubnetMask = $SubnetMask
} | Export-Csv C:\Temp\PSPSubnetMask.csv -Append

在本节中，在else之前缺少一个大括号，在函数末尾有一个额外的}：

   Write-Verbose "$serverName has /24 configuration, logged"

 else {
     Write-Verbose "$serverName already has a /23 configuration"
 } #Else

用于列出/ 24子网的所有服务器的脚本
