Bitlocker 851 the system cannot find the path specified

Hi everyone,

 

We are trying to migrate computers from domain joined to INTUNE.

Every time we disjoin a computer the BitLocker has a problem suspending or even disabling and re-enabling.

What we found is an error 851 the system cannot find the file specified.

When we rejoin to The domain and enable BitLocker the error does not happen and BitLocker is enabled successfully.

We also use a pin with the boot up.

I tried searching the issue and attempted the repairs suggested with no luck.

 

Any ideas would be appreciated.

    Since you're using a PIN with boot up, it's possible that the Boot Manager is becoming corrupted when disjoining from the domain. The Boot Manager is responsible for managing the boot process, including BitLocker. You can try to repair the Boot Manager using the following command in an elevated Command Prompt: bcdboot C:\Windows /s C: /f ALL.

    Before exiting the volume, use the

    manage-bde -protectors -delete C: -type tpm and manage-bde -off C:

    commands to fully decrypt and remove the BitLocker protector.
