NS_E_WMP_DRM_NEW_HARDWARE
Start with the producing object
NS_E_WMP_DRM_NEW_HARDWARE means machine binding changed enough that previously stored rights no longer validate against the current hardware identity. 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.
A useful test is to compare hardware-change history and the license-store machine binding without altering either.
Relevant runtime state
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 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: machine binding changed enough that previously stored rights no longer validate against the current hardware identity. Other content or actions may still be valid.
Do not diagnose the wrong layer
Machine binding changed enough that previously stored rights no longer validate against the current hardware identity.
One-variable comparison
The before/after comparison has one controlled variable. Before correction, machine binding changed enough that previously stored rights no longer validate against the current hardware identity; after correction, the same workflow can use the issuer’s reauthorization or license-recovery procedure for the changed machine. The result model is suitable for a regression fixture because its expected state change is observable without weakening the DRM policy.
Trace requirements
| Field | Value |
|---|---|
| Direct check | compare hardware-change history and the license-store machine binding without altering either |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by this result |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence this result |
Practical diagnostic path
- Preserve it and
0xC00D11D6before cleanup, fallback or another media item changes the context. - Compare the failure with a known-good case that changes only the property named by this condition: machine binding changed enough that previously stored rights no longer validate against the current hardware identity.
- Apply the targeted fix: use the issuer’s reauthorization or license-recovery procedure for the changed machine.
- Associate this result with the current Windows Media Player rights-processing object and the requested action.
- Run the direct check: compare hardware-change history and the license-store machine binding without altering either.
What another code would mean
| Result | Why it points elsewhere |
|---|---|
NS_E_WMP_DRM_NEEDS_AUTHORIZATION | the Player DRM components require an online authorization or security update before the action can continue |
NS_E_WMP_LICENSE_RESTRICTS | the content license explicitly prohibits the selected Player action |
NS_E_WMP_DRM_INVALID_SIG | a required DRM component or protected object fails signature validation in the Player path |
What success looks like
Repair the owner of the check: use the issuer’s reauthorization or license-recovery procedure for the changed machine.
