STATUS_TPM_INVALID_FAMILY
STATUS_TPM_INVALID_FAMILY is a Windows NTSTATUS value in the TPM facility. For STATUS_TPM_INVALID_FAMILY, 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 delegation groups permissions into families. This status means the family identifier supplied to a delegation-management command is not valid for the TPM owner state or for the current delegation table.
The error often appears when software replays cached delegation metadata after owner clear, ownership change, table reset or migration to another TPM. The family ID is not a portable application identifier.
Diagnostic focus
- Log the family ID and the owner/delegation table generation used by the caller.
- Refresh delegation metadata after TPM owner changes or administrative resets.
- Compare with STATUS_TPM_DELEGATE_FAMILY, which reports an attempt to manage a family outside the delegated scope.
