NS_E_DRM_INDIV_SERVICE_UNAVAILABLE
The first reliable fact
The condition encoded by 0xC00D2845 is not generic playback failure; it is that the client cannot reach a functioning individualization service. Diagnosis of NS_E_DRM_INDIV_SERVICE_UNAVAILABLE therefore starts in Windows Media DRM client internals, the layer responsible for the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.
Use the failing operation itself to separate network/TLS reachability from an explicit service-unavailable response. 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_INDIV_SERVICE_UNAVAILABLE from neighboring Windows Media errors.
The transaction to reconstruct
NS_E_DRM_INDIV_SERVICE_UNAVAILABLE is meaningful only while the following state remains associated with one operation: DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Preserve the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting failure for NS_E_DRM_INDIV_SERVICE_UNAVAILABLE.
This evidence matters because the rejected condition is specifically that the client cannot reach a functioning individualization service.
What the result does not prove
For NS_E_DRM_INDIV_SERVICE_UNAVAILABLE, the established fact is that the client cannot reach a functioning individualization service. For NS_E_DRM_INDIV_SERVICE_UNAVAILABLE, 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_INDIV_SERVICE_UNAVAILABLE as the first specific result. The object and operation attached to NS_E_DRM_INDIV_SERVICE_UNAVAILABLE are usually more diagnostic than a later cleanup or user-interface summary.
A controlled before/after test
NS_E_DRM_INDIV_SERVICE_UNAVAILABLE should be modeled as a failed precondition, not as an arbitrary media exception. Demonstrate the precondition by choosing to separate network/TLS reachability from an explicit service-unavailable response, and remove it by choosing to restore connectivity or wait for service recovery before individualizing. Keeping the NS_E_DRM_INDIV_SERVICE_UNAVAILABLE transition intact also shows whether a retry reused stale state or actually reevaluated the corrected input.
Incident data
| Field | Value for NS_E_DRM_INDIV_SERVICE_UNAVAILABLE |
|---|---|
| Owner | operation, API/callback, object or session identifier, and component/device version associated with NS_E_DRM_INDIV_SERVICE_UNAVAILABLE |
| Direct check | separate network/TLS reachability from an explicit service-unavailable response |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by NS_E_DRM_INDIV_SERVICE_UNAVAILABLE |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence NS_E_DRM_INDIV_SERVICE_UNAVAILABLE |
| Lower result | the earliest store, network, cryptographic, driver or provider status preceding the final NS_E_DRM_INDIV_SERVICE_UNAVAILABLE wrapper |
Reproduce at the owning layer
- Preserve
NS_E_DRM_INDIV_SERVICE_UNAVAILABLEand0xC00D2845before cleanup, fallback or another media item changes the context. - Apply the narrow correction for
NS_E_DRM_INDIV_SERVICE_UNAVAILABLE: restore connectivity or wait for service recovery before individualizing. - Associate
NS_E_DRM_INDIV_SERVICE_UNAVAILABLEwith its current Windows Media DRM client internals object and the requested action. - Run the direct check for
NS_E_DRM_INDIV_SERVICE_UNAVAILABLE: separate network/TLS reachability from an explicit service-unavailable response. - Compare the failure with a known-good case that changes only the property named by this condition: the client cannot reach a functioning individualization service.
- Repeat the same action with the same content/device identity and verify that
NS_E_DRM_INDIV_SERVICE_UNAVAILABLEis not replaced by another policy or trust failure.
Do not merge these failures
| Result | Why it points elsewhere |
|---|---|
NS_E_DRM_INDIV_FRAUD | the individualization service rate-limited further security upgrades for this client/day |
NS_E_DRM_INDIV_NO_CABS | the individualization service cannot supply the required component packages |
NS_E_DRM_RESTORE_SERVICE_UNAVAILABLE | the remote license-restore service is unavailable during a restore transaction |
Restore the required state
Recovery should change the failed precondition by choosing to restore connectivity or wait for service recovery before individualizing. For NS_E_DRM_INDIV_SERVICE_UNAVAILABLE, success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- While investigating NS_E_DRM_INDIV_SERVICE_UNAVAILABLE, keep this restriction: Do not replace DRM binaries or registry state before recording their versions and signatures; otherwise a component mismatch and a damaged license object become indistinguishable.
- Do not alter trusted time, revocation enforcement, certificate validation or output policy merely to suppress
NS_E_DRM_INDIV_SERVICE_UNAVAILABLE; that bypasses the decision instead of correcting its input. - Retain one failing artifact and one corrected artifact so the resolution of
NS_E_DRM_INDIV_SERVICE_UNAVAILABLEcan be regression-tested.
Keep a diagnostic fixture
For the final NS_E_DRM_INDIV_SERVICE_UNAVAILABLE 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_INDIV_SERVICE_UNAVAILABLE 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.
