NS_E_DRM_LIC_NEEDS_DEVICE_CLOCK_SET
The exact DRM condition
NS_E_DRM_LIC_NEEDS_DEVICE_CLOCK_SET is Windows Media DRM HRESULT 0xC00D2779. It identifies the selected license requires a secure secure clock that has not been set. The useful scope is the device-facing path that authenticates a WMDRM-capable device, obtains its certificate and secure clock, evaluates transfer policy, and records metering or registration state; it is not a generic statement that the media player, network or file system failed.
Record license time policy and clock state initialization state.
The surrounding protocol and store state
A device can be reachable as storage while still failing WMDRM authentication, secure-clock or policy requirements. Time-bound and subscription licenses may require a trusted device time; changing the host clock does not repair a secure clock that was never obtained or set.
Evidence worth preserving
- Protected identity: secure clock value, source and last successful update.
- Operation state: requested transfer/burn action and license restriction.
- Persistence or transport: device activation, registration and metering result.
- Security context: device model, firmware and WMDRM capability.
- Correlation point: device certificate chain and serial identity.
Related codes and the diagnostic split
| Result | Different condition |
|---|---|
NS_E_DEVICE_NOT_WMDRM_DEVICE | The attached device does not advertise the WMDRM capability required by this transfer. |
NS_E_DRM_TRANSFER_CHAINED_LICENSES_UNSUPPORTED | The requested device transfer does not support the selected chained-license relationship. |
NS_E_DRM_POLICY_METERING_DISABLED | The content requires metering but metering is disabled for the client or device path. |
Diagnostic sequence
- Prove the boundary by ensuring you can record license time policy and device time initialization state.
- After you set the secure clock through the supported online DRM workflow, verify both the requested right and the final store/device state.
Correcting the producing condition
Resolve the underlying condition directly: set the clock state through the supported online DRM workflow. A player reinstall, reboot or new license request is useful only when it changes the condition “lic needs device time set” and can be verified against the original evidence.
Representative case: A subscription track cannot be synchronized to a newly reset device.
Regression check
Repeat the operation that originally returned this result. Assert the exact HRESULT at the producing API in the failing “lic needs secure clock set” fixture; then change only the relevant precondition and confirm that the corrected run completes without substituting a neighboring DRM result. After correcting it, verify the requested action and the final license-store, secure-clock, device or migration state relevant to “lic needs clock state set”.
Code-specific operational note
The user-facing message “The file could not be transferred because the device time is not set.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
