It is recommended to save the BitLocker key in a safe place like inside the Active Directory, because if the hard disk fail or not accessible you will lose the key or at least backup it inside the Active Directory. Join domain and enable BitLocker is possible using the PowerShell and to save drive you may use Backup-BitLockerKeyProtector, have a look at:
