We have this same problem. We have Intuit's hosting service through Right Networks, and we also installed on our in-house network server. Intuits response is this is a Right Network issue and Right Networks said this is an Intuit issue. Complete run around. I was able to send the return in through our in-house network. Proseries obviously have an issue and are not letting preparers know there is an issue. We pay enough for this program this is unacceptable.
