TPM_E_DAA_ISSUER_SETTINGS
Read the result in context
TPM_E_DAA_ISSUER_SETTINGS (0x80280053) belongs to TPM 1.2 Direct Anonymous Attestation. The base What Is page already shows the short Windows message; the additional diagnostic value is that this result marks the DAA issuer settings supplied to the TPM fail a consistency or integrity check.
The first producer to identify for this HRESULT is the staged DAA enrollment or signing state machine. Direct Anonymous Attestation in TPM 1.2 is a multi-stage protocol. Each stage consumes issuer data, TPM-specific state and outputs from earlier stages, so the first inconsistent transcript element is more useful than the final generic application failure.
The result value 0x80280053 should remain attached to the symbolic name. Some this result logs store the value as a negative signed integer; others expose only a generic CNG, WMI, BitLocker or enrollment message. Neither substitution identifies the DAA issuer settings supplied to the TPM fail a consistency or integrity check as precisely as it.
Fields worth decoding
- Producer for this HRESULT: the staged DAA enrollment or signing state machine.
- Rejected invariant: the DAA issuer settings supplied to the TPM fail a consistency or integrity check.
- Decisive capture: DAA_issuerSettings structure, issuer public parameters, digest bindings, version, provisioning source, and current stage.
- Safe comparison: validate the issuer package independently and compare with a newly issued test package from the same authority.
Controlled comparison
Build the result minimal case around the original command contract. Use a disposable object when the request can write NV data, advance a counter, change authorization state or consume a lock transition. The comparison is valid only when the caller, TPM generation and security policy remain the same.
| Question | Evidence for this HRESULT |
|---|---|
| What exact state was rejected? | the DAA issuer settings supplied to the TPM fail a consistency or integrity check |
| Which layer owns the result? | The staged DAA enrollment or signing state machine. |
| What must be correlated? | DAA_issuerSettings structure, issuer public parameters, digest bindings, version, provisioning source, and current stage |
| What is the controlled comparison? | validate the issuer package independently and compare with a newly issued test package from the same authority |
Adjacent failure boundaries
| Constant | Checkpoint represented by its standard message |
|---|---|
TPM_E_DAA_TPM_SETTINGS | The consistency check on DAA_tpmSpecific has failed — a separate checkpoint when compared with this result. |
TPM_E_DAA_INPUT_DATA1 | The consistency check on DAA parameter inputData1 has failed — a separate checkpoint when compared with this result. |
TPM_E_DAA_STAGE | The atomic process indicated by the submitted DAA command is not the expected process — a separate checkpoint when compared with it. |
The codes above may appear in the same workflow, but they are not aliases. TPM_E_DAA_ISSUER_VALIDITY concerns the later issuer-validity check rather than the settings structure itself.
Repair without destroying evidence
Replace corrupted or mismatched issuer settings and restart enrollment; do not reuse partial daa state. Do not mix values from separate DAA attempts. The protocol is staged and transcript-bound; substituting one issuer value or nonce can make every later stage misleading.
Proof for this HRESULT consists of a successful replay plus validation of the intended key, PCR, NV, context, event-log, provider or service result. A software fallback or a newly provisioned blank TPM answers a different question than it.
