PowerShell：清单报告显示每个 AD 域控制器的安装日期数据为空白

Question

我正在尝试获取单个 AD 域的每个 Active Directory (AD) 域控制器的操作系统安装日期作为清单报告的一部分。感谢 this article，下面代码块中显示的所有内容都可以在任何 AD 环境中运行。但是，“安装日期”列在网格视图中显示空白数据。要获得安装日期，它需要一个 PS-远程会话到每个目标域控制器。经过大量研究后不确定我在这方面做错了什么，所以在这里发帖。

# Import AD module
Import-Module ActiveDirectory
 
# Get your ad domain
$DomainName = (Get-ADDomain).DNSRoot
 
$AllDCs = Get-ADDomainController -Filter * -Server $DomainName | Select-Object Hostname,Ipv4address,isGlobalCatalog,Site,Forest,OperatingSystem

如评论中所述，您需要：

确保您在目标 DC 上实际执行了 Invoke-Command 语句，方法是：
- 围绕{...}中的语句（创建一个脚本块，而不是在本地执行）
- 将 -ComputerName $DC.Hostname 传递给 Invoke-Command
将该调用的输出分配给 $InstallDate

ForEach($DC in $AllDCs)
{
    $ping = ping $DC.Hostname -n 1 | Where-Object {$_ -match "Reply" -or $_ -match "Request timed out" -or $_ -match "Destination host unreachable"}
    switch ($ping)
    {
        {$_ -like "Reply*" }                          { $PingStatus = "Success" }
        {$_ -like "Request timed out*"}               { $PingStatus = "Timeout" }
        {$_ -like "Destination host unreachable*"}    { $PingStatus = "Unreachable" }
        default                                       { $PingStatus = "Unknown" }
    }  

    $InstallDate = if($PingStatus -eq 'Success'){
        Invoke-Command { (Get-WmiObject Win32_OperatingSystem).ConvertToDateTime( (Get-WmiObject Win32_OperatingSystem).InstallDate )) } -ComputerName $DC.Hostname
    }
         
    $DCTable.Rows.Add(  $DC.Hostname,
                        $DC.Ipv4address,
                        $DC.isGlobalCatalog,
                        $DC.Site,
                        $DC.Forest,
                        $DC.OperatingSystem,
                        $PingStatus,
                        $InstallDate
                              
                        )| Out-Null
    # ...

}
