NS_E_DRM_UNABLE_TO_CREATE_PROPERTIES_OBJECT
The failing WMDRM boundary
0xC00D2734 maps to NS_E_DRM_UNABLE_TO_CREATE_PROPERTIES_OBJECT. Read it as a result from Windows Media DRM client API contract and object lifecycle: the DRM runtime cannot create the property-access object required for this operation. Keeping the “unable to create properties object” boundary intact for it prevents a later playback message from hiding the original DRM failure.
The built-in message summarizes the user-visible outcome, while the symbolic phrase “unable to create properties object” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
Place in the DRM workflow
The workflow around this result matters: 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. In addition, many operations are asynchronous and stateful, so object lifetime and completion ordering are part of the API contract.
State to capture before retry
Capture the first occurrence before retry or teardown changes state. The smallest useful record contains:
- Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Protected identity: property name, type, size and initialization order.
- Operation state: operation state, callback sequence and cancellation owner.
- Persistence or transport: first inner HRESULT before an application replaces it with a generic error.
- Security context: exact interface method and object type being created.
- Correlation point: SDK/runtime version and linked DRM stub library.
Prefer IDs, hashes, sizes, and timestamps. Never log keys, passwords, licenses, or decrypted media.
A useful investigation order
- Locate the earliest API return, callback or event containing this result and
0xC00D2734. - Identify the exact content, license, store, device or migration object generation involved in “unable to create properties object”.
- Determine whether “unable to create properties object” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
- Perform the code-specific check: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Make one narrow correction — correct component/version or initialization state and create a fresh property-access object — and repeat the same producing operation.
Narrow remediation
The corrective direction is to correct component/version or initialization state and create a fresh property-access object. Preserve the original content/header, store or migration material for it until the operation succeeds and survives a fresh application object or required restart.
Representative case: The application reaches the property-access stage but object construction fails before any content or server work begins.
Nearby results with different meanings
| Result | Different boundary |
|---|---|
NS_E_DRM_UNABLE_TO_CREATE_INDI_OBJECT | The DRM runtime cannot create the individualization object required for this operation. |
NS_E_DRM_UNABLE_TO_CREATE_LICENSE_OBJECT | The DRM runtime cannot create the license-management object required for this operation. |
NS_E_DRM_PARAMETERS_MISMATCHED | Related DRM parameters describe different content, license, operation or object state. |
Order the result event chain by timestamp; prefer the earliest specific result.
Verification after correction
After the repair, recreate the WMDRM object and run the smallest reproducer for it. Confirm that 0xC00D2734 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it.
What the missing object would have owned
In the path, the properties object normally reads and writes the DRM attributes used by content, license and client operations. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary.
For this object specifically, preserve the property identifier, expected type, size and owning object. A successful fix should create a new properties object and then complete its first real operation, not merely make the factory call return a different generic error.
