Bitlocker – Fix Recovery Information Backup to Active Directory Issue

active-directorybitlockerencryption

cmd illustration

I have a device that needs to have its' bitlocker recovery backup up to AD for visibility in the "Bitlocker Recovery" tab of the object in Active Directory.

I found that the device only had a TPM protector. So I added a Numerical Password. I want to backup this numerical password to AD.

I run manage-bde protectors c: -adbackup -ID '{my-id-goes-here}'. Windows replies with:
Recovery information was successfully backed up to Active Directory.

I pull up ADUC, find the device, look at it's 'Bitlocker Recovery' tab only to find that there is nothing here.

ADUC

I also tried:

$BLV = Get-BitLockerVolume -MountPoint "C:"
Backup-BitLockerKeyProtector -MountPoint "C:" -KeyProtectorId $BLV.KeyProtector[1].KeyProtectorId

getting a 0 exit code, but nothing published to AD. Is there something I'm missing here?

There only difference I see between machines that CAN Have it pushed to AD this way and this device is the 'Conversion Status' field:

a machine that works is 'Fully-Encrypted' instead of 'Only Used Space'

a machine that works is 'Fully-Encrypted' instead of 'Only Used Space'

A machine that works is 'Fully-Encrypted' instead of 'Only Used Space'.

How can I get this password backed up to AD?

"Numerical Password" is not what is backed up to AD. You need to add a "Recovery Key", like this:

Add-BitLockerKeyProtector -MountPoint C: -RecoveryPasswordProtector
