Problem with LAN and Dial-Out at same time

-----Original Message-----
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,
