PowerShell and Get-QADComputer

PowerShell and Get-QADComputerPowerShell get-Computer

The Get-QADComputer cmdlet has some unexpected parameters.  For example, you can check which operating system, and which service pack is installed on each of your servers.  If you have not used the QAD cmdlets before, it may be best to start with QADUser.

Topics for PowerShell’s Get-QADComputer


Pre-requisites, particularly for the QAD snap-In

Before we can get my examples to work you need to meet these pre-requisites.

  1. Download and install PowerShell and .Net Framework. 
    Go to Microsoft’s site and choose the flavour to suit your operating system.
  2. Download, then install the QAD Snap-Ins from this site:
  3. Register the snap-In. (Key point)
    add-PSSnapin quest.activeroles.admanagement
  4. Gain access to Active Directory.  Best would be to logon at a domain controller in a test domain.

Example 1:  List the properties of Get-QADComputer

Before we tackle the main task, let us research which interesting parameters to include in our script.

 Get-QADComputer | Get-Member 

Note 1:  Get-Member (or gm) reveals a rich selection of properties, for example, ComputerRole, OSVersion and OSServicePack.

Example 2: List the computers in your domain, and their properties

Important: You need to change yourDom/ to reflect the name of your domain.  If you are in any doubt check with Active Directory Users and Computers.

# PowerShell script to list computers, including DCs
# Author: Guy Thomas
# Version 1.2 August 2008 tested on PowerShell v 1.0
$OU = "yourDom/"
Get-QADComputer -searchRoot $OU -searchScope ‘SubTree’ `
| Format-Table name, ComputerRole, Path, OSVersion, OSServicePack -auto

Note 1:  I suggest you try my parallel learning technique and match the user properties revealed by QADComputer, with the property sheet that you see in Active Directory Users and Computers.  Look in the Domain Controllers folder, as well as the Computers folder.

Drill down with -SearchScope

SearchScope is a modifier for -SearchRoot.  While we have used the value ‘SubTree’, it is also possible to substitute ‘OneLevel’, or even ‘Base’.

Help getting to know QADComputer

 Get-Command | Where {$_.name -Match "QADComputer"}

Note 1:  A mild surprise, there is no ‘set’ cmdlet, just the one verb, ‘get’.  Consequently you cannot add descriptions to a computer object using these quest cmdlets.

Real-life Task: Updating Computer Descriptions

The situation:  Paul Ku needed to update the ldap description field for his servers.

Preparation:  Paul employed a spreadsheet to store the server names and their corresponding descriptions.  Key point, Paul produced a csv file (called serverdescriptions.csv)

# Title: Update Server Description
# Desc: Import the server descriptions from a spreadsheet
# Author: Paul Ku
# Date: Nov 3 2008

# Serverdescriptions.csv contains 2 columns with headers,
# Server, Descriptions respectively.
# Each row contains "Server name", "Role or description"

import-csv serverdescriptions.csv |
foreach $_ {Get-qadcomputer $_.server |
set-qadobject -description $_.description}
