NS_E_DRM_CLIENT_CODE_EXPIRED

Meaning in the active workflow

The first actionable fact in NS_E_DRM_CLIENT_CODE_EXPIRED is that the DRM client security code is outside its accepted validity period. The subsystem producing this result is Windows Media DRM client internals, not the media decoder; it performs the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.

Confirm the producer by doing one thing first: verify trusted system time and record client component version/signature.

Preserve the original generation

The security decision represented by this result depends on DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Record the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting failure from the same attempt.

This evidence matters because the rejected condition is specifically that the DRM client security code is outside its accepted validity period.

What remains unknown

The DRM client security code is outside its accepted validity period.

Failure model

It should be modeled as a failed precondition, not as an arbitrary media exception. Demonstrate the precondition by choosing to verify trusted system time and record client component version/signature, and remove it by choosing to install the supported current DRM/Player component rather than backdating the clock. The result model is suitable for a regression fixture because its expected state change is observable without weakening the DRM policy.

Diagnostic checklist

Field	Value
Direct check	verify trusted system time and record client component version/signature

Confirm the condition

Preserve it and 0xC00D2847 before cleanup, fallback or another media item changes the context.
Run the direct check: verify trusted system time and record client component version/signature.
Compare the failure with a known-good case that changes only the property named by this condition: the DRM client security code is outside its accepted validity period.
Apply the targeted fix: install the supported current DRM/Player component rather than backdating the clock.
Associate it with its current Windows Media DRM client internals object and the requested action.

Compare neighboring states

Result	Why it points elsewhere
`NS_E_DRM_INDIV_SERVICE_UNAVAILABLE`	the client cannot reach a functioning individualization service
`NS_E_DRM_RESTORE_SERVICE_UNAVAILABLE`	the remote license-restore service is unavailable during a restore transaction
`NS_E_DRM_NO_UPLINK_LICENSE`	a chained license references a root/uplink license that is absent from the available license set

Operational response

Repair the owner of the check: install the supported current DRM/Player component rather than backdating the clock.

Preserve the evidence before making changes.
