Usage requirementsBitlocker-Recovery-AD

To view recovery passwords, you must be a domain administrator, or you must have been delegated permissions by a domain administrator. In addition, to use the BitLocker Recovery Password Viewer, the following requirements must be met:

  • The domain must be configured to store BitLocker recovery information.
  • The computers protected by BitLocker must be joined to the domain.
  • BitLocker Drive Encryption must have been enabled on the computers.

Bitlocker Recovery Password viewer for Active Directory

Retrieving a BitLocker key from Active Directory involves using the BitLocker Recovery Password Viewer for Active Directory Users and Computers tool. This tool allows you to locate and view BitLocker recovery passwords, assuming that you have Domain Administrator privileges in the domain in which the password is stored and the passwords are archived in AD. You can obtain this tool from Microsoft’s website here:

http://support.microsoft.com/kb/928202

The tool is not included with Windows Server 2008 or Windows Vista by default. So although you can archive BitLocker keys to AD, there isn’t any way to retrieve them unless you download and install this tool.

After you have installed it but before you actually run the tool on a DC for the first time, it is important that you run the command

regsvr32.exe bdeaducext.dll.

The tool itself modifies Active Directory Users and Computers so that when you view a computer account’s properties, there will be a BitLocker Recovery Tab that lists BitLocker recovery passwords associated with the computer account.
