NS_E_DRM_PD_TOO_MANY_DEVICES

Failure scope

For NS_E_DRM_PD_TOO_MANY_DEVICES, the failed contract is that portable-media registration data already contains the maximum supported target-device set. Within Windows Media DRM client internals, this result is raised while processing the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.

The strongest confirmation is to enumerate registered devices and last-validation times before deleting any entry.

Test without erasing evidence

Preserve this result and 0xC00D2842 before cleanup, fallback or another media item changes the context.
Associate this result with its current Windows Media DRM client internals object and the requested action.
Run the direct check: enumerate registered devices and last-validation times before deleting any entry.
Compare the failure with a known-good case that changes only the property named by this condition: portable-media registration data already contains the maximum supported target-device set.
Apply the targeted fix: remove obsolete registrations through the supported management interface.

Data worth retaining

The important objects are DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Evidence should correlate the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting failure.

That observation distinguishes it from file corruption because portable-media registration data already contains the maximum supported target-device set.

The transition to retest

The transition that returns it begins with enumerate registered devices and last-validation times before deleting any entry. If that observation matches, the next state cannot be reached until the implementation can remove obsolete registrations through the supported management interface. Use a known-good counterpart only as a control; do not replace the failing artifact before its identifiers and hashes are recorded.

Verification inputs

Direct check	enumerate registered devices and last-validation times before deleting any entry

Different owners, similar dialog

Result	Why it points elsewhere
`NS_E_DRM_LICENSE_SERVER_INFO_MISSING`	the client cannot read configuration that identifies or describes the license service
`NS_E_DRM_BUSY`	another process or operation holds the DRM subsystem lock
`NS_E_DRM_INDIV_FRAUD`	the individualization service rate-limited further security upgrades for this client/day

Separate cause from wrapper

Portable-media registration data already contains the maximum supported target-device set.

When a retry is valid

A matching correction is to remove obsolete registrations through the supported management interface.

Preserve the evidence before making changes.
