What does HRESULT 0xC00D274B (NS_E_DRM_CACHED_CONTENT_ERROR) mean?

NS_E_DRM_CACHED_CONTENT_ERROR

What this HRESULT isolates

The symbolic result NS_E_DRM_CACHED_CONTENT_ERROR narrows 0xC00D274B to license validity, rights and policy enforcement. In practical terms, Windows Media Digital Rights Management (DRM) cannot play the protected file because you do not have the appropriate rights; the producing layer is the evaluation step that matches a license to protected content and decides whether the requested action is allowed under dates, counters, application security, device registration and output restrictions.

Record the exact API, object state, input identity and first lower-level result associated with this failure.

Which component owns the failure

Do not flatten this result into a generic DRM error. Possessing a license does not imply that every operation is permitted; rights and restrictions are evaluated for the requested action. The second relevant rule is that the same content can have several licenses, so diagnostics must identify the license actually selected by the DRM component.

Diagnostic inputs that separate the causes

• Protected identity: requested action such as play, copy, burn or transfer.
• Operation state: license ID, KID and content-header identity.
• Persistence or transport: valid-from, expiration and secure-clock values.
• Security context: application security level and required output protection.
• Correlation point: remaining counts, device registration and revocation state.

How to prove the condition

1. Start from 0xC00D274B and map it to the first WMDRM object that returned it.
2. Separate content/header evidence, license evidence, machine/device evidence and service/network evidence around “cached-content DRM failure”.
3. Before retrying this result, check whether another “cached-content DRM failure” operation was active or whether the previous result may have committed partially.
4. Record the exact API, object state, input identity and first lower-level result associated with the failing operation.
5. Apply the smallest supported fix: correct the producing DRM state or input and retry with a fresh operation object; avoid resetting unrelated protected state.

What a supported fix should change

The supported response to this result is narrow: correct the producing DRM state or input and retry with a fresh operation object. After correcting it, reopen or recreate the object that owned “cached-content DRM failure” so the verification does not reuse state from the failed operation.

Representative case: The application reaches this path and receives this exact HRESULT before the higher-level media action can complete.

Do not merge these HRESULTs

How to know the fix is real

A valid regression has two fixtures: one that deliberately produces “Windows Media Digital Rights Management (DRM) cannot play the protected file because you do not have the appropriate rights” and one that applies the targeted correction. Compare callback order, selected license/KID, final rights decision and persistence state; disappearance of the “cached-content DRM failure” dialog alone is not proof.

Code-specific operational note

The user-facing message “Windows Media Digital Rights Management (DRM) cannot play the protected file because you do not have the appropriate rights.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
