What does HRESULT 0x80280050 (TPM_E_DAA_RESOURCES) mean?

TPM_E_DAA_RESOURCES

TPM_E_DAA_RESOURCES: diagnose the owning boundary

TPM_E_DAA_RESOURCES (0x80280050) is documented as The DAA command has no resources availble to execute the command. Treat that wording as the specific TPM 1.2 DAA resource availability boundary; it is more useful than a generic “component failed” label.

Evidence that matters

Record DAA session handles/resources and current stage. Release stale sessions or complete the active flow before starting another DAA operation.

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_RESOURCES.
