Outlook tries to dial while connect to LAN

[ChuckW]

Hi,

I am trying to set up Outlook to work with our LAN. I set
up an outlook account for someone and set the Connection
under properties to "Connect using a Local Area Network".
Despite this Outlook continues to try to dial up rather
than connecting through the DSL modem that we have at our
office. A dial up box appears as if I were at home using
a modem. I test Internet Explorer which also goes through
this same DSL modem and it does work. Does anyone know
how to solve this problem?

Thanks,

Chuck
