FVE_E_ADBACKUP_NOT_ENABLED
The failed prerequisite
FVE_E_ADBACKUP_NOT_ENABLED / 0x803100D5 marks a rejected BitLocker transition: effective policy prevents recovery information for this drive type from being backed up to Active Directory Domain Services.
For FVE_E_ADBACKUP_NOT_ENABLED, note: A managed restriction is part of the security design. When diagnosing FVE_E_ADBACKUP_NOT_ENABLED, remember: Record which authority delivered it and whether the requested operation is mandatory for compliance or merely a convenience feature.
Diagnostic map
| Layer | policy and authorization |
|---|---|
| Proof to collect | drive type, effective recovery-backup policy, domain join, escrow target, policy source and attempted backup method |
| Different condition | an AD connectivity, schema or permission failure after backup is allowed |
| First safe change | enable the correct AD DS backup policy centrally or use another approved escrow destination before depending on the protector |
For FVE_E_ADBACKUP_NOT_ENABLED, note: BitLocker evaluates the target volume together with effective Group Policy or MDM policy, Windows edition, caller authorization and the requested protector or management method. When diagnosing FVE_E_ADBACKUP_NOT_ENABLED, remember: A policy HRESULT therefore describes a rejected configuration decision, not evidence that encrypted sectors are damaged.
A focused verification sequence
- For
FVE_E_ADBACKUP_NOT_ENABLED, record drive type, effective recovery-backup policy, domain join, escrow target, policy source and attempted backup method. ForFVE_E_ADBACKUP_NOT_ENABLED, keep the full HRESULT and the first method that returned it because later cleanup calls can report a different state. - For
FVE_E_ADBACKUP_NOT_ENABLED, capturemanage-bde -statusand the protector inventory for the exact volume GUID, not only the drive letter, because letters can change in WinRE, clusters and deployment environments. - Export BitLocker operational events for the
FVE_E_ADBACKUP_NOT_ENABLEDfailure and note the boot session, caller identity and management source; that evidence separates this BitLocker condition from a generic access or storage error.
Recommended operational response
- For
FVE_E_ADBACKUP_NOT_ENABLED, enable the correct AD DS backup policy centrally or use another approved escrow destination before depending on the protector. - After correcting the
FVE_E_ADBACKUP_NOT_ENABLEDprerequisite, refresh protection, conversion and lock state before one controlled retry; a cached UI message is not proof that theFVE_E_ADBACKUP_NOT_ENABLEDcondition is still active. - Before a
FVE_E_ADBACKUP_NOT_ENABLEDremediation deletes protectors, changes firmware mode, resizes partitions or decrypts a production drive, verify that an independent recovery method is available and escrowed in the intended directory or account.

Interpretation checkpoint
FVE_E_ADBACKUP_NOT_ENABLED identifies a condition but not every owner of the surrounding state. Preserve the original caller, volume GUID and event sequence so the correction is applied at the right layer.
State checks specific to FVE_E_ADBACKUP_NOT_ENABLED
| Checkpoint | How to interpret it for FVE_E_ADBACKUP_NOT_ENABLED |
|---|---|
| Before the call | Record the target identity and the pre-call policy and authorization state. For FVE_E_ADBACKUP_NOT_ENABLED, the decisive boundary is that effective policy prevents recovery information for this drive type from being backed up to Active Directory Domain Services. |
| At failure | Preserve drive type, effective recovery-backup policy, domain join, escrow target, policy source and attempted backup method. This proves whether FVE_E_ADBACKUP_NOT_ENABLED came from BitLocker itself or from a wrapper translating another result. |
| After correction | Enable the correct AD DS backup policy centrally or use another approved escrow destination before depending on the protector. The FVE_E_ADBACKUP_NOT_ENABLED request should then advance without removing an unrelated recovery route. |
| After reboot or remount | Recheck protection, conversion and lock state for FVE_E_ADBACKUP_NOT_ENABLED; a successful management call is incomplete if the next boot cannot unlock the volume. |
Verification after the change
For FVE_E_ADBACKUP_NOT_ENABLED, success means more than the absence of a dialog. Confirm that the condition represented by FVE_E_ADBACKUP_NOT_ENABLED now matches the intended design, that the protector inventory has not lost an independent recovery route, and that the next reboot or remount can unlock the volume. If the FVE_E_ADBACKUP_NOT_ENABLED request advances to another HRESULT, record both values in order because that transition reveals the next unmet prerequisite.
