NS_E_WMP_DRM_NO_RIGHTS
The exact DRM boundary
This HRESULT is specific: NS_E_WMP_DRM_NO_RIGHTS appears because none of the available media usage rights authorizes the requested Player operation. The owner is Windows Media Player rights processing; its working contract covers 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.
The shortest path to a defensible diagnosis is to enumerate action-specific license state for play, burn, rip and sync independently.
What to log
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.
This evidence matters because the rejected condition is specifically that none of the available media usage rights authorizes the requested Player operation.
Troubleshooting order
- Preserve this result and
0xC00D11DCbefore cleanup, fallback or another media item changes the context. - Run the direct check for this HRESULT: enumerate action-specific license state for play, burn, rip and sync independently.
- Compare the failure with a known-good case that changes only the property named by this condition: none of the available media usage rights authorizes the requested Player operation.
- Apply the narrow correction for this HRESULT: obtain the missing right or remove the unavailable action from the user flow.
- Associate this result with its current Windows Media Player rights processing object and the requested action.
- Repeat the same action with the same content/device identity and verify that it is not replaced by another policy or trust failure.
Expected state change
A useful failure model for this HRESULT links cause and recovery: none of the available media usage rights authorizes the requested Player operation. Verify that model when you enumerate action-specific license state for play, burn, rip and sync independently, then make the smallest change needed to obtain the missing right or remove the unavailable action from the user flow. The result model is suitable for a regression fixture because its expected state change is observable without weakening the DRM policy.
Scope and consequences
The established fact is that none of the available media usage rights authorizes the requested Player operation. 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 it as the first specific result. The object and operation attached to it are usually more diagnostic than a later cleanup or user-interface summary.
Fields for a reproducible report
| Field | Value |
|---|---|
| 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 |
| Owner | operation, API/callback, object or session identifier, and component/device version associated with it |
| Direct check | enumerate action-specific license state for play, burn, rip and sync independently |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by it |
Related codes, different contracts
| Result | Why it points elsewhere |
|---|---|
NS_E_WMP_DRM_GENERIC_LICENSE_FAILURE | the Player wrapper could not reduce a rights-validation failure to a more specific public result |
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_INDIV_FAILED | the Player’s DRM security-component individualization did not complete successfully |
Change the rejected precondition
Correct this layer directly and obtain the missing right or remove the unavailable action from the user flow. Success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- A broad reset is not the first step for this HRESULT; 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.
Closure criterion
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.
