NS_E_WMP_DRM_INDIV_FAILED
Why the symbolic result matters
When NS_E_WMP_DRM_INDIV_FAILED is returned, the system has already established that the Player’s DRM security-component individualization did not complete successfully. Within Windows Media Player rights processing, this result is raised while processing the Player layer that opens protected media, queries the local license state, performs silent or interactive rights acquisition, validates DRM components and applies play, burn or sync restrictions.
Confirm the producer by doing one thing first: capture the individualization stage, service response class and component version.
Objects involved
Do not separate this result from its owning state: content KID and header, license-store entry, requested action, acquisition URL, user/store context, secure clock and DRM component generation. The diagnostic record for this HRESULT is the content KID, requested action, license-state query, acquisition callback sequence, server response category and the first lower-level DRM HRESULT.
The scope stays narrow: the Player’s DRM security-component individualization did not complete successfully. Other content or actions may still be valid.
First failure versus cleanup
The established fact is that the Player’s DRM security-component individualization did not complete successfully. That fact does not independently establish damaged media bytes, a missing decoder, a generally broken network, or invalid rights for every other action.
If the Player, encoder, setup program or device layer later emits a broader error, retain this result as the first specific result. The object and operation attached to it are usually more diagnostic than a later cleanup or user-interface summary.
Cause and successor state
It should be modeled as a failed precondition, not as an arbitrary media exception. Demonstrate the precondition by choosing to capture the individualization stage, service response class and component version, and remove it by choosing to resolve connectivity or component integrity and rerun the supported security-upgrade workflow. The result comparison should preserve content and device identity so success cannot be attributed to testing a different asset.
What separates this code
| Field | Value |
|---|---|
| Owner | operation, API/callback, object or session identifier, and component/device version associated with it |
| Direct check | capture the individualization stage, service response class and component version |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by it |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence it |
| Lower result | the earliest store, network, cryptographic, driver or provider status preceding the final it wrapper |
Verification sequence
- Preserve it and
0xC00D11DDbefore cleanup, fallback or another media item changes the context. - Apply the narrow correction for this HRESULT: resolve connectivity or component integrity and rerun the supported security-upgrade workflow.
- Associate it with its current Windows Media Player rights processing object and the requested action.
- Run the direct check for this HRESULT: capture the individualization stage, service response class and component version.
- Compare the failure with a known-good case that changes only the property named by this condition: the Player’s DRM security-component individualization did not complete successfully.
- Repeat the same action with the same content/device identity and verify that it is not replaced by another policy or trust failure.
Adjacent HRESULTs
| Result | Why it points elsewhere |
|---|---|
NS_E_WMP_DRM_NO_SECURE_CLOCK | a device-dependent license requires trusted time but the target device has no usable secure clock state |
NS_E_WMP_DRM_NO_RIGHTS | none of the available media usage rights authorizes the requested Player operation |
NS_E_WMP_DRM_COMPONENT_FAILURE | a DRM component failed internally after the Player had selected the protected-content path |
Safe recovery
A matching correction is to resolve connectivity or component integrity and rerun the supported security-upgrade workflow. Success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- It: Do not reset the local DRM store before recording the content KID and license-state result; a reset can turn a precise rights or signature failure into a generic missing-license condition.
- Do not alter trusted time, revocation enforcement, certificate validation or output policy merely to suppress it; that bypasses the decision instead of correcting its input.
- Retain one failing artifact and one corrected artifact so the resolution of it can be regression-tested.
A useful automated test
For the final it test, keep the content KID or file hash, requested action, user/account, device identity and output route unchanged wherever they apply.
