BitLocker key asking on every reboot

I have a laptop in domain and it running window 10 version 1709 with TPM 2.0. After encrypting the drive the bitlocker key keep prompting on every reboot. The same works well with another 2 Laptops one running with WIndow 10 version 1709 TPM 1.2 and the other running Windows 10 version 1703 TPM 2.0. . I had read that form version 1709 changes were made in bit locker features. I tried most of the basic stuff shown online but no luck. Please let me know if anyone faced the same and any solutions or workaround is there for this.

Hi Jefferson,

Tnx for the reply. I had tried the same laptop  with windows 10 version 1703 and 1709, in which the bitlocker encrypts the HDD perfectly fine with any issue, the problem comes when i reboot. the one with version 1703 reboots without asking for bitlocker key and the the one with version 1709 asks top enter the bitlocker key on every reboot.. i tried disabling and enabling the bitlocker by running this command 

<manage-bde.exe -protectors -disable C:>

<manage-bde.exe -protectors -enable C:>

I had also ready that in windows 10 version 1709 changes were made in bitlocker features

Do let me know abt any updates or solutions on this.

Regards,

Akram
