Hello, hoping for some help from with a strange issue I have on a customer site I am currently unable to build Dell Optiplex 5040 devices with Windows 10 1909 x64 Enterprise from an Endpoint manager 1910 MDT integrated task sequence. The task sequence fails when trying to execute the Invoke-MbamClientDeployment.ps1 script. I have detailed the high level tasks below and attached the SMSTS.log. BIOS upgraded to latest version BIOS Reset to factory settings BIOS Password Set BIOS Standard config applied UEFI Boot enabled TPM Cleared & activated TPM Converted from 1.2 to 2.0 TPM Cleared again and reactivated OS Deployed Drivers deployed MBAM TPMPassTheHash step completed DOTNET Enabled C++ Redists applied Security Patches Applied The MBAM Group MBAM_XTS_AES256 applied to reg PreBoot Input Protectors for Tablets applied to reg MDOP MBAM 2.5 SP1 Installed MBAM Client Hot Fix KB4505175 Applied Sleep 2 mins DisableRootAutoUpdate (Certificate applied) Restart Set PowerShell Execution Policy Set to bypass Set PowerShell Execution Policy powershell.exe -command Initialize-TPM Is run **THE STEP THAT FAILS** Invoke-MbamClientDeployment.ps1 with the below parameters Parameters - -RecoveryServiceEndpoint "https://MBAM:443/MBAMRecoveryAndHardwareService/CoreService.svc" -StatusReportingServiceEndpoint "https://MBAM:443/MBAMComplianceStatusService/StatusReportingService.svc" –IgnoreEscrowOwnerAuthFailure -EncryptionMethod "XTSAES256" **The Post Steps** Reset TPM Policy EnableRootAutoUpdate The TPM status is Enabled, Activate & NOT owned The above works on all other models tested but fails on the 5040 The actual error message received is contained in the smsts.log file attached and the extract is below. The device is also in a staging OU that receives no Group Policy. The device does register in MBAM if continue on error is checked on the offending task and the computer object moved to the correct OU but will not encrypt. The same task sequence works on the other Dell models tested e.g. 5050 I have logged in after and BitLocker throws a internal error if you try to run it manually. **THE ENVIRONMENT**** A single site deployment of Endpoint Manager 1910 with two distribution points deploying Windows 10 1909 x64 enterprise with a MDT Integrated task sequence. The Dell command tool kit has been integrated into End Point Manager and drives the BIOS/TPM config steps in the task sequence. The Dell TPM conversion tool is used to convert the TPM to 2.0. The devices been build are production Windows 7 and are been repurposed as Windows 10 x64 Enterprise 1909

Hello, I am new here but I have been following windows-noob.com for a very long time. You have amazing content. I am Running SCCM 2012 R2 SP1 CU2 environment with MDT 2012 SP1 integrated plus I have WADK 10.0.10240.16384. I have build a Task Sequence below which works flawless on Dell OptiPlex 7040 and E5450. The only issue I have is when the deployment is completed. The bitlocker is not enabled and TPM says " tpm is ready for use with reduced functionality". TPM is enabled in BIOS, UEFI is selected, Secure Boot is enabled as well. Any help is appreciated on how to initiate TPM during OSD and enable bitlocker. Thanks for all the help
