NS_E_DRM_CERTIFICATE_REVOKED
Read the code before the dialog
The producer of 0xC00D28A1 has determined that the WMDRM-ND peer certificate is explicitly revoked. The subsystem producing NS_E_DRM_CERTIFICATE_REVOKED is WMDRM for Network Devices, not the media decoder; it performs the transmitter/receiver protocol that registers a network playback device, approves it, validates proximity, opens a protected session and transcrypts licensed content for that receiver.
The shortest path to a defensible diagnosis is to record certificate serial number, CRL version and revocation entry. The standard AllStat text is already shown above; this custom section concentrates on the object state and the evidence needed to separate NS_E_DRM_CERTIFICATE_REVOKED from neighboring Windows Media errors.
Correlate the owner and the policy
NS_E_DRM_CERTIFICATE_REVOKED is meaningful only while the following state remains associated with one operation: device certificate and serial number, registration-database entry, approval flag, validation timestamp, network session, protocol message and transcrypt policy. Preserve the exact WMDRM-ND message type, device identifier, certificate chain, registration state, round-trip timing and the first protocol HRESULT for NS_E_DRM_CERTIFICATE_REVOKED.
The producing layer has not made a claim about every media operation; it has only established that the WMDRM-ND peer certificate is explicitly revoked.
A controlled reproduction
- Preserve
NS_E_DRM_CERTIFICATE_REVOKEDand0xC00D28A1before cleanup, fallback or another media item changes the context. - Associate
NS_E_DRM_CERTIFICATE_REVOKEDwith its current WMDRM for Network Devices object and the requested action. - Run the direct check for
NS_E_DRM_CERTIFICATE_REVOKED: record certificate serial number, CRL version and revocation entry. - Compare the failure with a known-good case that changes only the property named by this condition: the WMDRM-ND peer certificate is explicitly revoked.
- Apply the narrow correction for
NS_E_DRM_CERTIFICATE_REVOKED: update/replace the revoked device identity; bypassing CRL checks is not a repair. - Repeat the same action with the same content/device identity and verify that
NS_E_DRM_CERTIFICATE_REVOKEDis not replaced by another policy or trust failure.
Why the first HRESULT matters
When documenting NS_E_DRM_CERTIFICATE_REVOKED, state the rejected input and the expected successor state. The rejected input is demonstrated when you record certificate serial number, CRL version and revocation entry; the successor becomes reachable after you update/replace the revoked device identity; bypassing CRL checks is not a repair. Keeping the NS_E_DRM_CERTIFICATE_REVOKED transition intact also shows whether a retry reused stale state or actually reevaluated the corrected input.
The final dialog can be broader
For NS_E_DRM_CERTIFICATE_REVOKED, the established fact is that the WMDRM-ND peer certificate is explicitly revoked. For NS_E_DRM_CERTIFICATE_REVOKED, 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 NS_E_DRM_CERTIFICATE_REVOKED as the first specific result. The object and operation attached to NS_E_DRM_CERTIFICATE_REVOKED are usually more diagnostic than a later cleanup or user-interface summary.
Minimum evidence set
| Field | Value for NS_E_DRM_CERTIFICATE_REVOKED |
|---|---|
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by NS_E_DRM_CERTIFICATE_REVOKED |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence NS_E_DRM_CERTIFICATE_REVOKED |
| Lower result | the earliest store, network, cryptographic, driver or provider status preceding the final NS_E_DRM_CERTIFICATE_REVOKED wrapper |
| Owner | operation, API/callback, object or session identifier, and component/device version associated with NS_E_DRM_CERTIFICATE_REVOKED |
| Direct check | record certificate serial number, CRL version and revocation entry |
Contrast with related results
| Result | Why it points elsewhere |
|---|---|
NS_E_DRM_INVALID_CERTIFICATE | the WMDRM-ND peer certificate is malformed, corrupted or fails signature validation |
NS_E_DRM_LICENSE_UNAVAILABLE | no license available to the transmitter authorizes the requested WMDRM-ND action |
NS_E_DRM_DEVICE_LIMIT_REACHED | the transmitter has reached the number of network devices allowed by policy or implementation |
Recovery at the right layer
The appropriate operational response is to update/replace the revoked device identity; bypassing CRL checks is not a repair. For NS_E_DRM_CERTIFICATE_REVOKED, success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- Evidence for
NS_E_DRM_CERTIFICATE_REVOKEDis easy to destroy; Do not delete the complete device-registration database before preserving the failing device record and certificate chain; that removes the distinction between registration, approval, validation and session failures. - Do not alter trusted time, revocation enforcement, certificate validation or output policy merely to suppress
NS_E_DRM_CERTIFICATE_REVOKED; that bypasses the decision instead of correcting its input. - Retain one failing artifact and one corrected artifact so the resolution of
NS_E_DRM_CERTIFICATE_REVOKEDcan be regression-tested.
Re-test the original case
For the final NS_E_DRM_CERTIFICATE_REVOKED test, keep the content KID or file hash, requested action, user/account, device identity and output route unchanged wherever they apply. The NS_E_DRM_CERTIFICATE_REVOKED case is resolved only when the operation completes without this HRESULT and without a substitute failure from a neighboring license, trust, session or policy check.
