BitLocker Deployment with Active Directory - How to Start Automatic Encryption

Description:

You deployed BitLocker using Active Directory only. You have setup the necessary Group Policy, run manual BitLocker Encryption and can see the recovery password is being store at Active Directory.

Now you are wondering how it could start auto encryption without user interaction.

Resolution:

From https://www.experts-exchange.com/articles/33771/We-have-bitlocker-so-we-need-MBAM-too.html we can see that we can create a task scheduler on the machine and run it with System credential.

Detail:

Task name: BL (name it as you want, but please don’t forget to change the name in the last script line)

Triggers: at logon of any user

Executing account: system

Action: powershell.exe with the argument \\server\share\BL.ps1

The script:

$pin=(Get-Random -Minimum 0 -Maximum 999999).ToString('000000')
echo "$pin" | out-file \\server\pins\$env:computername.txt -Append
$SecureString = ConvertTo-SecureString "$pin" -AsPlainText -Force
Add-BitlockerKeyProtector -MountPoint "C:" -Pin $SecureString -TPMandPinProtector
manage-bde -on c: -s -used -rp
