How do I automatically unlock a E drive when the system connects to the domain with Bitlocker?

I have Windows 2008 R2 System with a C and E drive.  The data drive (E drive) is encrypted with Bitlocker and everytime we reboot this server I have to run the command "manage-bde -unlock e: -pw".  When I hit enter I enter the password at the prompt and hit enter again to unlock the drive.

Is there a way that I can have this drive automatically unlocked during the boot up process after it authenticates to Active Directory?  If so what steps do I need to make this happen?

Thanks
