NS_E_WMP_DRM_NO_SECURE_CLOCK
The state behind the HRESULT
NS_E_WMP_DRM_NO_SECURE_CLOCK belongs to the point where a device-dependent license requires trusted time but the target device has no usable secure clock state. This result runs inside Windows Media Player rights processing, where the implementation handles 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 query the device DRM status and secure-clock flag before starting transfer.
Build a useful incident record
The important objects are content KID and header, license-store entry, requested action, acquisition URL, user/store context, secure clock and DRM component generation. Evidence for this HRESULT should correlate 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: a device-dependent license requires trusted time but the target device has no usable secure clock state. Other content or actions may still be valid.
Reconstruct the decision
Reconstruct the transition from the requested action to the rejected condition. The proof step is to query the device DRM status and secure-clock flag before starting transfer; the repaired transition must then perform the supported device data/clock update while online, then re-evaluate the license. Record the first lower-layer status beside this result because wrapper HRESULTs can otherwise conceal the producing component.
State table
| Field | Value |
|---|---|
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence this result |
| 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 | query the device DRM status and secure-clock flag before starting transfer |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by it |
Focused verification
- Preserve it and
0xC00D11DBbefore cleanup, fallback or another media item changes the context. - Apply the narrow correction for this HRESULT: perform the supported device data/clock update while online, then re-evaluate the license.
- Associate it with its current Windows Media Player rights processing object and the requested action.
- Run the direct check for this HRESULT: query the device DRM status and secure-clock flag before starting transfer.
- Compare the failure with a known-good case that changes only the property named by this condition: a device-dependent license requires trusted time but the target device has no usable secure clock state.
- Repeat the same action with the same content/device identity and verify that it is not replaced by another policy or trust failure.
Interpretation limits
The established fact is that a device-dependent license requires trusted time but the target device has no usable secure clock state. 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.
Neighboring security decisions
| Result | Why it points elsewhere |
|---|---|
NS_E_WMP_DRM_CANNOT_RESTORE | the Player restore service rejected another restore within its rate or policy limit |
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_RIGHTS | none of the available media usage rights authorizes the requested Player operation |
Repair criterion
Repair the owner of the check: perform the supported device data/clock update while online, then re-evaluate the license. 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.
Acceptance condition
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.
