Problem with LAN and Dial-Out at same time

[Reed]

We need to connect to Internet via office LAN (T-1 to ISP), and
dial out to another ISP to access a "private" network, using
provided PAL dialer.

We have one XP PC that was installed about 6 months ago and works
as desired (both connections active at same time). AFAIK nothing
"special" was done to make it work.

We are trying setup a second XP machine, accessing same LAN and
same private dial network. It will not consistently allow both
connections to be active. Some times it will, mostly it wont.

Main symptom is the LAN connection cannot access Internet when the
dial app is brought up. We have tried to see any differences in
configs, so far nothing appears different. We have found by trial
and error that we can "force" it to work by resetting the
"metrics" values in the LAN connection while dial is up, but this
does not permanently fix problem. LAN dies again if dial is
dropped and brought up again.

If you were configuring an XP PC from scratch to allow both
connections, what would need to be changed from defaults in LAN
Connection, and/or Dial Connection, or somewhere else ??

TIA,
Reed

I suspect that the dial-up connection is becoming the default gateway,
which is used to access the Internet. To prevent that:

1. Right click the dial-up connection.
2. Click Properties.
3. Click Networking.
4. Click "Internet Protocol (TCP/IP)".
5. Click Properties.
6. Click Advanced.
7. Un-check "Use default gateway on remote network".

The effect of un-checking "Use default gateway on remote network"
for the dial connection was to lose connection with the private
site we are connecting to.

FWIW, the working PC has this box checked.
