NS_E_DRM_NOT_CONFIGURED
How to classify this result
The symbolic result NS_E_DRM_NOT_CONFIGURED narrows 0xC00D2764 to Windows Media DRM client API contract and object lifecycle. In practical terms, required DRM properties have not all been supplied for the intended operation; the producing layer is the application-facing layer that initializes DRM support, validates parameters and properties, creates specialized objects, and delivers asynchronous status to the caller.
List required properties and record which one is unset at object activation.
How to prove the condition
- Locate the earliest API return, callback or event containing this result and
0xC00D2764. - Identify the exact content, license, store, device or migration object instance involved in “not configured”.
- Determine whether “not configured” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
- Make one targeted change — set the complete documented property set before starting the operation — and repeat the same producing operation.
Which component owns the failure
Do not flatten this result into a generic DRM error. The DRM client exposes different objects for license management, individualization, encryption, backup, metering and device registration; failure to create one object does not prove that all DRM state is damaged. The second relevant rule is that many operations are asynchronous and stateful, so object lifetime and completion ordering are part of the API contract.
Diagnostic inputs that separate the causes
- Protected identity: first inner HRESULT before an application replaces it with a generic error.
- Operation state: exact interface method and object type being created.
- Persistence or transport: SDK/runtime version and linked DRM stub library.
- Security context: property name, type, size and initialization order.
- Correlation point: operation state, callback sequence and cancellation owner.
For the “not configured” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. Do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs.
Common but unsafe responses
- Avoid retrying object creation in a loop without preserving the first HRESULT and runtime versions.
- Avoid replacing the DRM HRESULT with a generic application exception before telemetry records it.
What a supported fix should change
To correct this, set the complete documented property set before starting the operation. Preserve the original content/header, store or migration material until the “not configured” operation succeeds and survives a fresh application object or required restart.
Representative case: An encryption session starts without content ID or license acquisition metadata.
Do not merge these HRESULTs
| Result | Different condition |
|---|---|
NS_E_DRM_UNABLE_TO_CREATE_AUTHENTICATION_OBJECT | The DRM runtime cannot create the authentication object required for this operation. |
NS_E_DRM_OPERATION_CANCELED | The active DRM operation was canceled before completion. |
NS_E_DRM_STORE_NOTALLSTORED | Some of the licenses could not be stored. |
Several values can accompany the “not configured” condition in one incident. Order the event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary.
How to know the fix is real
After the repair, recreate the WMDRM object and run the smallest reproducer. Confirm that 0xC00D2764 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it.
Code-specific operational note
The user-facing message “Not all of the necessary properties for DRM have been set.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
