Storing Bitlocker Key to AD using MDT

Task:

How to enable Bitlocker and store the recovery key to AD? Using Windows 2008 MDT server, Windwos 7 clients, Windows 2003 domain.

Problem:

Seems to be something I am missing from all the information available to Enable Bitlocker and store the recovery key to AD.

Steps Taken:

1) Follwed the BitLocker Drive Encryption Configuration Guide: Backing Up BitLocker and TPM Recovery Information to Active Directory

• http://technet.microsoft.com/en-us/library/cc766015(WS.10).aspx

2) Verified that Bitlocker key is stored to AD by logging on as a Domain Admin on a Win 7 box, Initializing TPM and Bitlocker, Ran the scripts successfully:

• Get-TPMOwnerInfo.vbs
• Get-BitLockerRecoveryInfo.vbs

3) Enabled the Bitlocker task in MDT 2010, as shown in here http://blogs.technet.com/blogfiles/deploymentguys/WindowsLiveWriter/HowtoconfigureBitLockeronadditionaldriv_D4F8/image_2.png

• Selected Drive to Encrypt = TPM Only
• Choose where to create the recovery key = AD

4) Using PXE boot started the Lite touch seq, selected the Bitlocker options, started the Win 7 install.

5) Bitlocker starts finishes encrypting the drive but no recovery key stored in AD.

What am I missing?

Thanks
