PENDING Windows 10 1703 - Bitlocker TPM Errors

[TG09NZ]

Hi all,
First time poster, so apologise in advance if I post incorrectly.
Currently building Windows 10 devices, some are upgrades from Windows 7 to Windows 10 and others are fresh Windows 10 using SCCM (MDT integrated).
This works as expected, but when I log in and check TPM Administration the following message show up
Reduced Functionality errors codes
0x400900 = The Device lock counter has not be created
0x2900 = The monotonic counter incremental during the boot has not been created

Do I need to do something in the Task Sequence to clear the protectors or clear TPM before BitLocker is enabled

Cheers all

I haven't come across this error till now. I will check my TS where I have enabled bitlocker and try to simulate this error.

Thank you, i believe I need to clear the TPM before enabling bitlocker.

I am using Dell Laptops by the way

At the moment in the Task Sequence I have after the "Setup Windows and Configure" and Restart Computer I have the Apply Dell BIOS Configuration.
Install HAPI
Clear BIOS Password
Enable TPM
Enable TPM ACPI
Enable TPM PPI Pro
Enable TPM PPI Depro
Restart
Disable LegacyBoot
Enable UEFI
Enable ACHI
Enable UEFI Stack
Enable Virtualisation
Enabled Secure Boot
Set BIOS Password

Further down the TS near the end I have enable bitlocker

I believe Yes. This is how my TS looks with Bitlocker enabled. Very much similar to the steps that you mentioned.

cheers for the reply.
In the TPM Administration in Window do you get any error codes? also do you use the Native Enabled BitLocker from the TS or use Manage-BDE?

I believe i need to update the TPM version - http://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=RF87D

to utilize the clear TPM PPiOverride so it does not prompt for F12 when it clears the TPM.

I am having an issueapplying the update via SCCM or manually. I am getting "Error: Unable to prepare the TPM update payload."

So believe I am back to square one as I need to clear the TPM owner first before applying the TPM 2.0 update

any ideas?
