Hi aph. I don't think you have done anything wrong, and it appears that you have checked the correct things. Unfortunately Autodisconnect is one of the less reliable aspects of Microsoft Dial Up Networking. I find it works sometimes and not others, and whether it works or not appears to depend in some way on the sequence of opening and closing IE and OE. I think part of the problem is Microsoft's idea of the meaning of "when connection may no longer be needed". If anyone has an answer, I'll be interested to hear it.
