我构建了一个 PowerShell 5.1 脚本来导出数据库中的所有用户并将所有数据保存到 CSV 文件中。该脚本允许您及时设置日期，以便您可以决定何时希望导出用户。

经过一些测试后，我意识到并非所有用户都已导出，经过进一步调查，我意识到该属性WhenChanged并不 WhenCreated存在于每个用户中。尽管 AD UI 显示了具有正确数据的属性，如下面的屏幕截图所示。

当我运行以下命令时：

Get-ADUser -filter * -Properties LastLogonDate, userPrincipalName, initials, WhenCreated, whenChanged | Select-Object userPrincipalName, initials, whenCreated, whenChanged 

我得到以下结果：

 userPrincipalName  initials whenCreated            whenChanged          
-----------------  -------- -----------            -----------

如您所见，尽管屏幕截图显示具有首字母 TT，但具有首字母 TT 的用户没有任何价值。尽管我今天创建了这个用户，并且在同一天更改了几个值。

问题

• 我错过了什么？
• 是 AD 本身的问题还是只是命令的问题？

我正在寻找访问 CUPS Web 界面的管理页面的权限。

我可以访问该页面，并且可以浏览该站点的大部分内容，但遗憾的是，管理页面仍然被远程资源锁定。

我确实设置了Allow from all并且Allow all现在到处都尝试过，但我仍然无法访问该页面。

我错过了什么？
