I have a friend whom I'm trying to help get her PC working properly when connected to a Linksys WRT54G Wireless Router she has recently installed.

Previously she didn't have a router, and her PC (which is running Vista) was connected directly to a Wired Country modem using a PPPoE connection.

I have got most things sorted, but there is one issue that is eluding me because I don't have Vista and hence cannot reproduce the problem she is describing:

1)  All Dial-up and other Network Connections have been deleted from her PC (on the advice of the iHUG support tech.) except for her Local Area Connection which uses a Realtek NIC (embedded on the motherboard).

2)  However, when starting up Windows Mail, it is still trying to use a non-existent connection (presumably the old one to Wired Country).

3)  I gave her instructions on how to fix this according to the settings used in Outlook Express.

4)  However, it seems as though Windows Mail is different in this regard, and I don't know the correct steps to give her from here.

If it had been up to me, I would not have suggested deleting all the connections until Windows Mail was configured correctly.  However, we are now caught between a rock and a hard place, so any advice will be very gratefully received.
