The DOT3SVC service updates the AutoConfig value with the session handle ID when DOT3SVC authentication succeeds. Additionally, the session handle ID increases by 1. All authentication failure events and reauthentication events that come from the miniport or from the network do not match the session ID. Therefore, these events are dropped.
