Description:

This WFP API requires an explicit transaction, but none is active in the session.

Previous	Next
STATUS_FWP_WRONG_SESSION	STATUS_FWP_TXN_IN_PROGRESS

STATUS_FWP_NO_TXN_IN_PROGRESS

The API requires a caller-controlled transaction boundary

STATUS_FWP_NO_TXN_IN_PROGRESS means the operation requires an explicit transaction instead of WFP’s normal implicit transaction behavior. The failure is about the state of the current engine session, not about a malformed filter or a failed packet classification.

Open a read/write transaction only around the related policy changes, then make the required calls and commit or abort based on their results. Record the begin, the individual WFP calls, and the decision to commit; otherwise, a retry can accidentally run in a different transaction context.

What to check

The API’s documented transaction requirement and the engine handle passed to it.
Whether FwpmTransactionBegin0 succeeded before the operation.
Whether a wrapper opened and closed a separate session or committed early.
The rollback plan if one of several related policy changes fails.
