Enable bitlocker silently ?

  • 1.  Enable bitlocker silently ?

    ​Hello,

    We have non AD W7 and W10 laptops that are used for work-from-home.

    I am trying to enable bitlocker remotely / silently on W7 first.

    I have been able to script the enabling / activation of TPM via Altiris;

    CCTK --tpm=on --valsetuppwd=xxxxxxxxx
    CCTK --tpmactivation=enabled --valsetuppwd=xxxxxxxx

    Reboot

    When I try to activate bitlocker using manage-bde;

    manage-bde c: -on

    I get the following;

    ERROR: The TPM cannot be used to protect this volume. The TPM does not have an owner set.

    When I try;

    manage-bde -tpm -o

    I get the following;
    ERROR: Parameter "-TakeOwnership" requires and argument.

     

    When I go to the bitlocker gui I am able to enable bitlocker. The only thing that I am prompted for is where to save recovery key / password. For testing purposes I printed to pdf. Selected next, skipped hardware testing and next again to start the encryption process.

    Is it possible to do this scripted / silently?

     

    For laptops that do have bitlocker enabled (manually / in person) I am able to retrieve the numerical ID and password for IT Security's records via Altiris scripts.

    manage-bde -protectors C: -get
