MDT 2010 - Setting the Computer Description in AD without a webservice

Posted by: johan

Quite a few people have asked my how to retrieve the computer description value from the MDT database or the deployment wizard, and then store it in Active Directory as well as on the local machine, system properties. So I decided it was time for a new posting...

This sample does not require a webservice, however, if you don't mind using a webservice, you can always use Maik Kosters execellent guide:

Setting the Computer Description in Active Directory during MDT Deployments
http://myitforum.com/cs2/blogs/maikkoster/archive/2009/12/14/setting-the-computer-description-in-active-directory-during-mdt-deployments.aspx

This article describes the following processes

1. Get the Computer Description value.
2. Store the Description value on the computer object in Active Directory
3. Store the Description value on the system properties of the local computer

Download the sample scripts

Step 1 - Get the Computer Description value.

Built-in to MDT you have two options for this, either by enabling the description feature in the deployment wizard or by storing the value in the MDT database

Option 1 - Enabling the computer description feature in the deployment wizard

1. Open DeployWiz_Definition_ENU.xml in your favorite editor, search for "Computer Description Format"
2. Remove the comments () around the paragraph starting with

   You can also give your computer a friendly description... see this image
    

    

3. Configure your customsettings.ini with the following (the Description field is on the same pane as Configure the computer name).
   [Settings]
   Priority=Default
   [Default]
   OSInstall=Y
   SkipComputerName=NO
   When you start the deployment wizard the configure computer name screen will look like this: 
    

   

 

Option 2 - Setting the value in the MDT database

If you have set the value in the MDT database, you need to either query the ComputerIdentity table (because the built-in view doesnt list the description value), or update the view. In this example I query the ComputerIdentity table directly.

You need to add a custom property into customsettings.ini for the description property, and I selected to also set the ComputerDescription value so that we are consistent with using the wizard which sets that value. Another option is to take care of that in the scripts, checking for either Description or ComputerDescription values, but it's a bit easier simply to setComputerDescription to be the Description value that we get from the database.Configure your customsettings.ini with the following:

[Settings]
Priority=CIdentity, Default
Properties=Description, ComputerDescription

[Default]
OSInstall=Y
ComputerDescription=%Description%

[CIdentity]
SQLServer=MDT01
Instance=SQLEXPRESS
Database=MDT
Netlib=DBNMPNTW
SQLShare=Logs$
Table=ComputerIdentity
Parameters=UUID, AssetTag, SerialNumber, MacAddress
ParameterCondition=OR

Step 2 - Store the Description value on the computer object in Active Directory

1. Download the sample scripts.
2. Copy ZTISetComputerDescriptionInAD.wsf to the scripts folder in your deployment share.
3. Create a custom action in the State Restore phase, any place will do, I added the action to the Custom Tasks group. Use the following settings
   Type:  Run Command Line
   Name:  Set Computer Description in Active Directory
   Command:  cscript.exe "%SCRIPTROOT%\ZTISetComputerDescriptionInAD.wsf"
   Runas:
   Load the user's profile: Selected
   Note: The account that you use must have permissions in Active Directory to modify computer object attributes.

    

Step 3 - Store the Description value on the system properties of the local computer

1. Download the sample scripts.
2. Copy ZTISetComputerDescriptionLocally.wsf to the scripts folder in your deployment share.
3. Create a custom action in the State Restore phase, any place will do, I added the action to the Custom Tasks group. Use the following settings
   Type:  Run Command Line
   Name:  Set Computer Description Locally
   Command:  cscript.exe "%SCRIPTROOT%\ZTISetComputerDescriptionLocally.wsf"
