How to integrate BitLocker with Active Directory Domain Services

---

Integrating BitLocker with Active Directory Domain Services (AD DS) allows you to leverage AD DS for key storage and management, simplifying BitLocker deployment and recovery processes. Here's a guide on how to integrate BitLocker with AD DS:

1. Prepare Active Directory:
   • Ensure that your Active Directory environment is healthy and properly configured.
   • Make sure that all domain controllers are running Windows Server 2008 or later, as BitLocker recovery information storage requires the BitLocker Recovery Password attribute, which was introduced in Windows Server 2008.
2. Configure Group Policy:
   • Open the Group Policy Management Console (GPMC).
   • Create or edit a Group Policy Object (GPO) that applies to the computers you want to enable BitLocker on.
   • Navigate to Computer Configuration > Policies > Administrative Templates > Windows Components > BitLocker Drive Encryption.
   • Enable the policies related to BitLocker, such as "Choose how BitLocker-protected operating system drives can be recovered."
   • Configure settings such as password complexity requirements, encryption methods, and backup options.
3. Enable BitLocker on Computers:
   • On the target computers, open an elevated command prompt or PowerShell window.
   • Run the command manage-bde -on C: -RecoveryPassword to enable BitLocker encryption on the operating system drive (replace "C:" with the appropriate drive letter if necessary).
   • This command activates BitLocker and stores the recovery key in AD DS.
4. Store BitLocker Recovery Keys in Active Directory:
   • When BitLocker is enabled with the -RecoveryPassword parameter, the recovery key is automatically stored in AD DS.
   • Ensure that the computer has write permissions to the appropriate container in AD DS to store the BitLocker recovery information. By default, domain-joined computers have the necessary permissions.
5. Verify BitLocker Recovery Keys in Active Directory:
   • Open Active Directory Users and Computers (ADUC) console.
   • Locate the computer object for the BitLocker-encrypted machine.
   • Go to the "BitLocker Recovery" tab to view the recovery keys stored in AD DS.
6. Recovery Operations:
   • In case of BitLocker recovery, such as a forgotten PIN or lost TPM, administrators can retrieve the recovery key from AD DS.
   • Use the BitLocker recovery key to unlock the encrypted drive and regain access to the data.
7. Monitor and Manage:
   • Regularly review BitLocker recovery information stored in AD DS.
   • Ensure that proper procedures are in place to handle BitLocker recovery events effectively.

By following these steps, you can integrate BitLocker with Active Directory Domain Services, enabling centralized management of BitLocker recovery keys and simplifying recovery operations.
