Question

我正在编写一个脚本来遍历我域中的所有计算机并显示其名称，描述和上次关机时间。这是一个更好的项目的开始，以更好地跟踪PC维护。到目前为止我的脚本运行得很好：

$strFilter = "computer"
$objDomain = New-Object System.DirectoryServices.DirectoryEntry
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.SearchScope = "Subtree" 
$objSearcher.PageSize = 1000 
$objSearcher.Filter = "(objectCategory=$strFilter)"
$colResults = $objSearcher.FindAll()
foreach ($i in $colResults)
{
    try{
        $wmi = $i.getDirectoryEntry()
        $lastShutdownTime = get-wmiobject -class Win32_OperatingSystem -computer $wmi.name
        $Description =  Get-WmiObject -Class Win32_OperatingSystem -computer $wmi.name |Select Description
        write-host $wmi.Name, $Description, $lastShutdownTime.convertToDateTime($lastShutdownTime.lastBootUpTime)
    }
    catch [system.exception]{

        "Could not reach $wmi.name"
    }
}

除非当我点击关闭的计算机时，我收到一个忽略我的try / catch块的错误。我如何写这个，以便它忽略当前关闭的计算机，或者至少不会对它们造成错误？

其他信息：遗憾的是，我无法使用AD模块。

将 -ErrorAction Stop 添加到get-wmiobject命令。变化：

$lastShutdownTime = get-wmiobject -class Win32_OperatingSystem -computer $wmi.name
$Description =  Get-WmiObject -Class Win32_OperatingSystem -computer $wmi.name |Select Description

到

$lastShutdownTime = get-wmiobject -class Win32_OperatingSystem -computer $wmi.name -ErrorAction Stop
$Description =  Get-WmiObject -Class Win32_OperatingSystem -computer $wmi.name -ErrorAction Stop |Select Description

循环遍历域中的计算机，但关闭的计算机除外
