What does HRESULT 0x80280056 (TPM_E_DAA_ISSUER_VALIDITY) mean?

TPM_E_DAA_ISSUER_VALIDITY

TPM_E_DAA_ISSUER_VALIDITY: diagnose the owning boundary

TPM_E_DAA_ISSUER_VALIDITY (0x80280056) is documented as The issuer's validity check has detected an inconsistency. Treat that wording as the specific TPM 1.2 DAA issuer validity check boundary; it is more useful than a generic “component failed” label.

Evidence that matters

Record issuer parameters, stage, transcript and TPM identity. Validate issuer data against the same session before retrying the DAA command.

Interpretation and verification

Keep the affected object and caller identity stable while changing only the rejected prerequisite. The correction is proven when the original operation crosses this boundary with the intended state or output. If a different HRESULT appears afterward, preserve it as a separate later-stage result rather than folding it back into TPM_E_DAA_ISSUER_VALIDITY.
