SL_REMAPPING_SP_PUB_TS_DATA_SIZE_TOO_BIG

How to read this result without losing context

0xC004D308 maps to SL_REMAPPING_SP_PUB_TS_DATA_SIZE_TOO_BIG. This result belongs to the trusted store and secure-timer layer and narrows the operation to the protected state store that keeps namespaced entries, attributes, secure timers, trusted time, hardware binding, rearm state and integrity breadcrumbs. In concrete terms, the value being stored exceeds the maximum data size for one trusted-store entry.

For triage, this belongs to the trusted store and secure-timer layer. The entry key can be valid and the store can have free capacity while this value is individually too large. Product-key changes or network tests are useful only when the evidence points back to those layers.

Minimum data for a reliable diagnosis

Where it sits in the licensing pipeline

Trusted-store results concern protected persistent state; deleting the store can erase the evidence that distinguishes missing data, capacity, access, binding and integrity failures. To verify this, capture requested data length, entry type, namespace and documented schema limit.

A positive trusted-time or rearm/recreation result must be interpreted by HRESULT severity and the subsequent license state, not by treating every nonzero value as a fatal error.

Adjacent states in the same subsystem

ResultDifferent condition
SL_REMAPPING_SP_PUB_TS_INVALID_HW_BINDINGCompared with this result, the trusted-store state no longer matches the machine hardware identity within allowed tolerance.
SL_REMAPPING_SP_PUB_TS_MAX_REARM_REACHEDCompared with this result, the protected rearm counter has reached the maximum permitted by licensing policy.
SL_REMAPPING_SP_PUB_TIMER_ALREADY_EXISTSCompared with it, creation was requested for a secure timer whose name already exists in the namespace.

A practical way to isolate the cause

  1. Record it, 0xC004D308, the exact API or service operation, and the affected product or protected object.
  2. Prove the specific condition: capture requested data length, entry type, namespace and documented schema limit.
  3. Compare the neighboring results below and identify which condition actually applies.

Actions that usually destroy useful evidence

What to repair—and what not to reset

Store only the supported compact value or split data using the owning component’s documented schema.

Representative case: A component tries to place an oversized diagnostic blob in a protected licensing entry.
