Get-ADGroup特定的ou

Question

我的代码：

$ADGroupList = (Get-ADGroup -Filter * -searchbase "OU=Staedte,DC=dmamgt,DC=local" -Properties *).Name

错误返回：

Get-ADGroup : Directory object not found
At C:\Users\Administrator\Documents\Ordner, Gruppen, Rechte.ps1:31 char:17
+ ... roupList = (Get-ADGroup -Filter * -searchbase "OU=Staedte,DC=dmamgt,D ...
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   + CategoryInfo          : ObjectNotFound: (:) [Get-ADGroup], ADIdentityNotFoundException
   + FullyQualifiedErrorId : ActiveDirectoryCmdlet:Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException,Microsoft.ActiveDir 
  ectory.Management.Commands.GetADGroup

有人能帮我吗？ 我不知道为什么它不起作用。
