STATUS_TPM_NO_WRAP_TRANSPORT
STATUS_TPM_NO_WRAP_TRANSPORT is a Windows NTSTATUS value in the TPM facility. For STATUS_TPM_NO_WRAP_TRANSPORT, it belongs to the TPM 1.2 error family and is normally surfaced through the Windows TPM stack, such as TPM Base Services, rather than by ordinary file, registry or network APIs.
TPM 1.2 transport sessions allow command streams to be wrapped and logged, but not every TPM, command or execution context permits that mode. This status points to the transport wrapper itself rather than to the inner command payload.
When it appears in a higher-level stack, inspect whether a library requested exclusive, logged or encrypted transport behavior automatically. The same TPM command can succeed when submitted directly but fail when the caller forces an unsupported wrapped-transport policy.
Diagnostic focus
- Record whether the command is being sent as a normal command or through a transport session.
- Check firmware capabilities before enabling transport wrapping as a default policy.
- If the inner command also fails without transport, diagnose that second result separately.
