Setup MDT 2013 (Update 2) to encrypt Windows 10 devices (Laptops) automaticlly

• A protector, which can either be stored in the Trusted Platform Module (TPM) chip, or stored as a password.
• To configure your environment for BitLocker, you will need to do the following:

1. Configure Active Directory for BitLocker.
2. Download the various BitLocker scripts and tools.
3. Configure the rules (CustomSettings.ini) for BitLocker.

Configure Active Directory for BitLocker

To enable BitLocker to store the recovery key and TPM information in Active Directory, you need to create a Group Policy for it in Active Directory. For this section, we are running Windows Server 2012 R2, so you do not need to extend the Schema. You do, however, need to set the appropriate permissions in Active Directory.

Note
Depending on the Active Directory Schema version, you might need to update the Schema before you can store BitLocker information in Active Directory.

In Windows Server 2012 R2 (as well as in Windows Server 2008 R2 and Windows Server 2012), you have access to the BitLocker Drive Encryption Administration Utilities features, which will help you manage BitLocker. When you install the features, the BitLocker Active Directory Recovery Password Viewer is included, and it extends Active Directory Users and Computers with BitLocker Recovery information.

Add the BitLocker Drive Encryption Administration Utilities

The BitLocker Drive Encryption Administration Utilities are added as features via Server Manager (or Windows PowerShell):

1. On DC01, log on as CONTOSO\Administrator, and, using Server Manager, click Add roles and features.
2. On the Before you begin page, click Next.
3. On the Select installation type page, select Role-based or feature-based installation, and click Next.
4. On the Select destination server page, select DC01.contoso.com and click Next.
5. On the Select server roles page, click Next.
6. On the Select features page, expand Remote Server Administration Tools, expand Feature Administration Tools, select the following features, and then click Next:
   1. BitLocker Drive Encryption Administration Utilities
   2. BitLocker Drive Encryption Tools
   3. BitLocker Recovery Password Viewer
7. On the Confirm installation selections page, click Install and then click Close.

Create the BitLocker Group Policy

Following these steps, you enable the backup of BitLocker and TPM recovery information to Active Directory. You also enable the policy for the TPM validation profile.

1. On DC01, using Group Policy Management, right-click the Contoso organizational unit (OU), and select Create a GPO in this domain, and Link it here.
2. Assign the name BitLocker Policy to the new Group Policy.
3. Expand the Contoso OU, right-click the BitLocker Policy, and select Edit. Configure the following policy settings:

   Computer Configuration / Policies / Administrative Templates / Windows Components / BitLocker Drive Encryption / Operating System Drives

   1. Enable the Choose how BitLocker-protected operating system drives can be recovered policy, and configure the following settings:
      1. Allow data recovery agent (default)
      2. Save BitLocker recovery information to Active Directory Domain Services (default)
      3. Do not enable BitLocker until recovery information is stored in AD DS for operating system drives (Do Not Enable This )
   2. Enable the Configure TPM platform validation profile for BIOS-based firmware configurations policy.
   3. Enable the Configure TPM platform validation profile for native UEFI firmware configurations policy.

      Computer Configuration / Policies / Administrative Templates / System / Trusted Platform Module Services

   4. Enable the Turn on TPM backup to Active Directory Domain Services policy.

(Don’t forget to disable Secure Boot & Enable the secure boot again after deployment is succes vol!!)

Set permissions in Active Directory for BitLocker

In addition to the Group Policy created previously, you need to configure permissions in Active Directory to be able to store the TPM recovery information. In these steps, we assume you have downloaded the Add-TPMSelfWriteACE.vbs script from Microsoft to C:\Setup\Scripts on DC01.

1. On DC01, start an elevated PowerShell prompt (run as Administrator).
2. Configure the permissions by running the following command:

   cscript C:\Setup\Scripts\Add-TPMSelfWriteACE.vbs

Add BIOS configuration tools from Dell, HP, and Lenovo

If you want to automate enabling the TPM chip as part of the deployment process, you need to download the vendor tools and add them to your task sequences, either directly or in a script wrapper.

Add tools from Dell

The Dell tools are available via the Dell Client Configuration Toolkit (CCTK). The executable file from Dell is named cctk.exe. Here is a sample command to enable TPM and set a BIOS password using the cctk.exe tool:

cctk.exe --tpm=on --valsetuppwd=Password1234

Add tools from HP

The HP tools are part of HP System Software Manager. The executable file from HP is named BiosConfigUtility.exe. This utility uses a configuration file for the BIOS settings. Here is a sample command to enable TPM and set a BIOS password using the BiosConfigUtility.exe tool:

BIOSConfigUtility.EXE /SetConfig:TPMEnable.REPSET /NewAdminPassword:Password1234

And the sample content of the TPMEnable.REPSET file:

English
Activate Embedded Security On Next Boot
*Enable
Embedded Security Activation Policy
*No prompts
F1 to Boot
Allow user to reject
Embedded Security Device Availability
*Available

Add tools from Lenovo

The Lenovo tools are a set of VBScripts available as part of the Lenovo BIOS Setup using Windows Management Instrumentation Deployment Guide. Lenovo also provides a separate download of the scripts. Here is a sample command to enable TPM using the Lenovo tools:

cscript.exe SetConfig.vbs SecurityChip Active

CustomSettings.ini
