What does HRESULT 0xC00D2756 (NS_E_DRM_SDMI_NOMORECOPIES) mean?

NS_E_DRM_SDMI_NOMORECOPIES

The failing WMDRM boundary

0xC00D2756 maps to NS_E_DRM_SDMI_NOMORECOPIES. Read it as a result from portable-device certificate, secure clock and transfer policy: the license copy count for the SDMI transfer has been exhausted. Keeping the “sdmi nomorecopies” boundary intact for NS_E_DRM_SDMI_NOMORECOPIES prevents a later playback message from hiding the original DRM failure, within the sdmi nomorecopies workflow.

For NS_E_DRM_SDMI_NOMORECOPIES, the built-in message summarizes the user-visible outcome, while the symbolic phrase “sdmi nomorecopies” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the selected license and remaining copy counter, in the sdmi nomorecopies path.

Place in the DRM workflow

The workflow around NS_E_DRM_SDMI_NOMORECOPIES matters: a device can be reachable as storage while still failing WMDRM authentication, secure-clock or policy requirements, while tracing sdmi nomorecopies. In addition, time-bound and subscription licenses may require a trusted device clock; changing the host clock does not repair a device clock that was never obtained or set, for the sdmi nomorecopies boundary.

State to capture before retry

Capture the first NS_E_DRM_SDMI_NOMORECOPIES occurrence before automatic retry, player teardown, store repair or license reacquisition changes the state, during sdmi nomorecopies diagnosis. The smallest useful record contains:

• Code-specific proof: record the selected license and remaining copy counter, in a sdmi nomorecopies incident.
• Protected identity: device model, firmware and WMDRM capability, for this sdmi nomorecopies result.
• Operation state: device certificate chain and serial identity, when reproducing sdmi nomorecopies.
• Persistence or transport: secure clock value, source and last successful update, within the sdmi nomorecopies workflow.
• Security context: requested transfer/burn action and license restriction, in the sdmi nomorecopies path.
• Correlation point: device activation, registration and metering result, while tracing sdmi nomorecopies.

For the “sdmi nomorecopies” investigation, use KIDs, license IDs, hashes, certificate thumbprints, sizes and timestamps where possible. While diagnosing NS_E_DRM_SDMI_NOMORECOPIES, do not place content keys, complete license blobs, passwords, cookies or decrypted media in ordinary logs, for the sdmi nomorecopies boundary.

A useful investigation order

1. Locate the earliest API return, callback or event containing NS_E_DRM_SDMI_NOMORECOPIES and 0xC00D2756.
2. For NS_E_DRM_SDMI_NOMORECOPIES, identify the exact content, license, store, device or migration object generation involved in “sdmi nomorecopies”.
3. For NS_E_DRM_SDMI_NOMORECOPIES, determine whether “sdmi nomorecopies” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
4. Perform the code-specific check: record the selected license and remaining copy counter, during sdmi nomorecopies diagnosis.
5. Make one narrow correction — obtain renewed rights; reconnecting or renaming the file cannot replenish the counter — and repeat the same producing operation, in a sdmi nomorecopies incident.

Narrow remediation

For NS_E_DRM_SDMI_NOMORECOPIES, the corrective direction is to obtain renewed rights; reconnecting or renaming the file cannot replenish the counter, for this sdmi nomorecopies result. Preserve the original content/header, store or migration material for NS_E_DRM_SDMI_NOMORECOPIES until the “sdmi nomorecopies” operation succeeds and survives a fresh application object or required restart.

Representative case: The final permitted portable-device copy has already been consumed, when reproducing sdmi nomorecopies.

What not to do first

• Avoid treating an unsupported-device result as a generic USB or file-copy failure, within the sdmi nomorecopies workflow. That changes evidence without demonstrating why NS_E_DRM_SDMI_NOMORECOPIES was produced.
• Avoid formatting the device before preserving its certificate, clock and firmware evidence, in the sdmi nomorecopies path. For NS_E_DRM_SDMI_NOMORECOPIES, that shortcut can create a second store, identity or policy problem, while tracing sdmi nomorecopies.
• Do not reduce NS_E_DRM_SDMI_NOMORECOPIES to “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity, for the sdmi nomorecopies boundary.

Nearby results with different meanings

Several values can accompany the “sdmi nomorecopies” condition in one incident. Order the NS_E_DRM_SDMI_NOMORECOPIES event chain by timestamp and prefer the first code produced at the lowest specific boundary over a later player-level summary, in the sdmi nomorecopies path.

Verification after correction

After the repair, recreate the WMDRM object and run the smallest reproducer for NS_E_DRM_SDMI_NOMORECOPIES. Confirm that 0xC00D2756 no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it, while tracing sdmi nomorecopies.

Code-specific operational note

The symbolic phrase “sdmi nomorecopies” is the important search and telemetry key for NS_E_DRM_SDMI_NOMORECOPIES. Keep it beside the exact value 0xC00D2756; the official message “You cannot make any more copies of this media file, for the sdmi nomorecopies boundary.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own, during sdmi nomorecopies diagnosis.
