Issue with OL 02 when sharing a connection

[Michelle]

Hi

I'm sharing an internet connection across a small LAN
(using 4 machines with XP Pro) and I'm having an issue
sending and receiving email on the three machines that
don't have the connection. It's looking for a network
password. It wasn't doing this originally but it is
now. Is there a way to stop it looking for the network
password as it doesn't need to.

I'm having no problem with the actual account because I
can send and receive on the 1 machine that connects
directly.

All help would be greatly appreciated
M.
