Question

当我运行以下脚本使用任务广告命令行开关提取OU信息时，它会给我一个错误，如下所示

Object reference not set to an instance of an object.
+ CategoryInfo          : NotSpecified: (:) [Get-QADComputer], NullReferenceException
+ FullyQualifiedErrorId : System.NullReferenceException,Quest.ActiveRoles.ArsPowerShellSnapIn.Powershell.Cmdlets.GetComputerCmdlet

以下是使用的脚本

$password = convertTo-secureString -string "123" -asPlainText -force 
$credential = new-object System.Management.automation.Pscredential ("test.com\sh" , $password) 
$session = New-PSSession -computername CI -credential $credential -port 5985 -Authentication Default
Invoke-Command -Session $session -ScriptBlock {
Add-PSSnapin Quest.ActiveRoles.ADManagement
$ou = get-qadcomputer QUAG | select -ExpandProperty canonicalname
}
$adou= (Invoke-Command -Session $session  -ScriptBlock { $ou })
Get-PSSession | Remove-PSSession
$adou

有人可以帮助我吗？

谢谢！

Answer 1

您无需在远程会话中运行QAD，您可以从管理站尝试：

Add-PSSnapin Quest.ActiveRoles.ADManagement
$pw = read-host "Enter password" -AsSecureString
Connect-QADService -Service 'server.company.com' -ConnectionAccount 'company\administrator' -ConnectionPassword $pw
Get-QADComputer QUAG | Select-Object -ExpandProperty CanonicalName

Answer 2

我认为问题在于您声明然后调用该脚本块的方式。没有经过测试，但我认为这可能会更好：

 Invoke-Command -Session $session -ScriptBlock {
 Add-PSSnapin Quest.ActiveRoles.ADManagement
       }
 $ou = {get-qadcomputer QUAG | select -ExpandProperty canonicalname}

 $adou= (Invoke-Command -Session $session  -ScriptBlock $ou)

无法在远程PS会话（Powershell）中查询[Get-QADComputer]信息
