Powershell - WMI＆AD對象

Question

有人可以請我解決以下問題或更好的方法來接近它 - 我所要做的就是返回有關所選服務器的一些信息，幷包含AD Description Field：

$cred = Get-Credential -Credential "test_user" 
$servername = "servername" 

[wmi]$os = Get-WmiObject -Class win32_operatingsystem -ComputerName $servername -Credential $cred 
[wmi]$cs = Get-WmiObject -Class win32_computersystem -ComputerName $servername -Credential $cred 
###[wmi]$ad = Get-ADComputer $servername -Properties Description -Credential $cred | Select-Object -Property description 

[hashtable]$osProperties = @{ 
    'Description' = $ad; 
    'OSVersion'=$os.version; 
    'OSBuild'=$os.buildnumber; 
    'SPVersion'=$os.servicepackmajorversion; 
    'Model'=$cs.model; 
    'Manufacturer'=$cs.manufacturer; 
    'RAM'=$cs.totalphysicalmemory/1GB -as [int]; 
    'Sockets'=$cs.numberofprocessors; 
    'Cores'=$cs.numberoflogicalprocessors; 
    'SystemType'=$cs.SystemType} 

$osproperties 

將返回：

Manufacturer     VMware, Inc.                                           
RAM       4                                              
OSVersion      6.1.7601                                            
SystemType      x64-based PC                                           
SPVersion      1                                              
Cores       2                                              
Model       VMware Virtual Platform

Sockets      2 

但是，如果我不選擇行get-adcomputer我得到以下錯誤：

Cannot convert value "@{description=PROD - Portsmouth - VM - W2K8R2 Monitoring Server}" to type "System.Management.ManagementObject". Error: "Cannot convert the "@{description=PROD - Portsmouth - VM - W2K8R2 
Monitoring Server}" value of type "Selected.Microsoft.ActiveDirectory.Management.ADComputer" to type "System.Management.ManagementObject"." 
At line:12 char:2 
+ [wmi]$ad = Get-ADComputer $servername -Properties Description -Credential $cred ...

    + CategoryInfo   : MetadataError: (:) [], ArgumentTransformationMetadataException 
    + FullyQualifiedErrorId : RuntimeException 

Answer 1

您有2個問題，我看到。首先是notjustme指出的那個。您正試圖將Get-AdComputer的輸出轉換爲WMI對象...因此出現錯誤。

在你回來的同一行上，並帶有描述的對象屬性。該行中的兩個小改動將使其餘代碼按預期工作。

$ad = Get-ADComputer $servername -Properties Description -Credential $cred | 
    Select-Object -ExpandProperty description

旁註

看看你的問題，看看我做了格式化你的代碼塊。使用文本框上方的「{}」按鈕創建縮進，將爲您節省大量時間。
