I am trying to resolve an issue with a computer which currently has Windows XP
Professional installed, and has both a broadband connection and a dial up
connection set up for internet access. Normally, the broadband connection is
used, but when the broadband service is down, the intention is to use the dial
up internet service provider for temporary internet connection use. This
computer is connected through a regular Linksys router to the broadband
connection's network outlet.

The problem is that when the dial up connection successfully connects, for some
reason it is not possible to access the internet with it. Previously, in my
experience with a similar set up on Windows 98SE, I found that after the dial up
connection is established, I could use all web browsers installed on the system
to start browsing via dial up. After the dial up connection is terminated, the
web browsers would automatically revert to using the broadband connection.

In the case of this Win XP Pro computer, it seems that the system cannot find
the dial up connection for internet access after the DUN connects successfully.
Even more strangely, there is no problem using the DUN to send outgoing mail via
the dial up internet service provider's SMTP outgoing mail server, and this
proves that the connection is working. However, all internet browsing using all
the web browsers installed on this system under Win XP Pro fails, as if the
system was unable to get DNS for browsing.

Are there any specific settings or parameters in my networking settings that I
need to adjust so that it would be easy to flip back and forth between broadband
and dial up? I have even disabled the broadband connection and then connected
with dial up, but was still unable to web browse. Thanks for any help.

Some of these parameters are not set correctly and should be adjusted.
