Problem with simultaneous Dial-up and DSL Connection on Windows-XP

[dj_wong]

Hi All,

I have a constant DSL connection to company network. With which I can
also connect to the internet. However in order to connect to a specific
application server I need to connect with modem dialup. Once dialup
network is established, in addition to the DSL network, I can not go to
any internet websites. Once I do
"route <ip-of-app-server> <ip-of-dialup>
I can connect to the application-server and Intranet-of-DSL network.
However I still cannot go to any Internet sites using Internet
Explorer. I'd greatly appreciate your help!!

We do have a proxy-configuration file configured in IE->Tools->Internet
Options->Connections->Lan Settings.
