powershell - 为什么远程计算机上的Powershell查询会引发访问被拒绝错误？

Question

当我在连接到远程计算机的计算机上执行简单的PowerShell查询时，我从PowerShell ISE中收到此类错误:

Get-WmiObject : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
At line:8 char:43
+                     $WmiOS = Get-WmiObject <<<<  -Class Win32_OperatingSystem -ComputerName    $targetComputer -credential $credential    
+ CategoryInfo          : NotSpecified: (:) [Get-WmiObject], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

You cannot call a method on a null-valued expression.
At line:9 char:45
+                     $WmiOS.ConvertToDateTime <<<< ($WmiOS.LastBootUpTime)            
+ CategoryInfo          : InvalidOperation: (ConvertToDateTime:String) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull

但是，相同的查询将在我的其他团队成员的计算机(或任何其他计算机)上正常工作，而不会出现任何问题。

我们尝试执行的脚本示例:

                $WmiOS = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $targetComputer -credential $credential    
                $WmiOS.ConvertToDateTime($WmiOS.LastBootUpTime)  

有任何想法吗？
