Bitlocker will not resume Windows 11 22H2

Question

Hello Technet community

 

We have been having problems with Windows 11 22H2 and Bitlocker since March 2023. With the latest update from June the problem is still there.

 

We install our devices with MEMCM, all devices are encrypted with Bitlocker but with different settings.

The Administration devices are encrypted with Bitlocker PIN and the recovery key is stored in the AD, we also use Bitlocker network unlock.

 

The Windows 11 22H2 Administration device is encrypted, but as soon as we apply the GPO for Bitlocker Network Unlock on the device and Bitlocker for Update is stopped, we get the following error message

The Windows 10 21H2 and 22H2 management devices work fine.

 

We have different models with this problem.

HP Elitebook x360 830 G7

HP Elitebook x360 830 G8

Dell Latitude 5590

 

Does anyone have any ideas? Please find attached the TPM and Bitlocker log files.

Thanks for the help and regards

Hello Alessandro,

Thank you for your question and for reaching out with your question today.

I can offer some general troubleshooting suggestions for the issue you're experiencing with BitLocker on Windows 11 22H2:

1. Verify TPM Firmware:
   • Ensure that the TPM (Trusted Platform Module) firmware on the affected devices is up to date. Check the manufacturer's website for any available firmware updates specifically designed for compatibility with Windows 11.
2. Check BitLocker Group Policy Settings:
   • Review the BitLocker Group Policy settings being applied to the Windows 11 devices. Verify that the settings are configured correctly and consistently across all affected devices.
   • Pay attention to any differences in the BitLocker Network Unlock settings between the working Windows 10 devices and the problematic Windows 11 devices.
3. Test with Different BitLocker Configuration:
   • Temporarily disable the BitLocker Network Unlock feature on the problematic Windows 11 devices and check if BitLocker functions as expected.
   • This will help determine if the issue is specifically related to the BitLocker Network Unlock feature or if it's a broader compatibility problem with BitLocker on Windows 11.
4. Update Device Drivers:
   • Ensure that all device drivers on the problematic Windows 11 devices are up to date. Outdated or incompatible drivers can sometimes cause issues with BitLocker functionality.
   • Visit the manufacturer's website for each device (HP and Dell) and download the latest drivers specifically designed for Windows 11.
5. Check Event Logs:
   • Review the event logs on the affected Windows 11 devices for any relevant error or warning messages related to BitLocker or TPM.
   • Look for any specific error codes or messages that could provide insights into the cause of the problem.
6. Engage Manufacturer Support:
   • If the issue persists and you've exhausted the troubleshooting steps, consider reaching out to the support teams of HP and Dell. They may have specific insights or guidance related to BitLocker compatibility issues on their devices running Windows 11.

These suggestions should help you get started with troubleshooting the BitLocker issue on Windows 11 22H2. Remember to exercise caution and create backups before making any changes to BitLocker settings or device configurations.
