SCCM 2002 and BitLocker management Client issue

Question

Sign in to vote

Hi,

I have deployed Bitlocker Policy to an client machine to set Biltocker. It does work fine. But every time if the client is rebooted , it is asking for Bitlocker Recovery KEY and not for PIN. I have turn off the Bitlocker and deployed again, the same result.

I have deleted the the machine policy no result.

Any Idea?

Regards

Discovering what is triggering a BitLocker recovery is tricky and varies depending on the hardware vendor and the TPM chip version being used. See https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn383583(v=ws.11)?redirectedfrom=MSDN#what-causes-bitlocker-recovery for more details.

I don't think we publish anything official about determining exactly what caused the recovery but you can review the BitLocker-API event log: https://docs.microsoft.com/en-us/windows/security/information-protection/bitlocker/troubleshoot-bitlocker#review-the-event-logs

Hi,

You can use the information in client event logs to help you troubleshoot issues with BitLocker management in Configuration Manager.
On a Configuration Manager client to which you deploy a BitLocker management policy, use the Windows Event Viewer to view BitLocker client event logs. Go to Applications and Services Logs, Microsoft, Windows, MBAM for both Admin and Operational event logs.
For more details, see:
Client event logs

The following list provides examples of specific events that will cause BitLocker to enter recovery mode when attempting to start the operating system drive(It seems more complicated and tricky for Windows 10):
