Question : Multi homed XP problem

I  have a workstation running XP Pro that has a credit card processing app running.  I have two internet connections available, one is through my company's lan and the other is a satellite modem.  I need to be able to have the satellite kick in if the lan internet connection goes down.  Would I use multi homing as a solution?  I am very new at this stuff and any help would be greatly appreciated.  Is it possible to have a nic automatically start if the primary nic fails?

Hi popaburgandy,

You can make it works by using multiple gateway with different metric cost (sometime it's called Dead Gateway Detection).
set your preferred Gateway a lower metric cost (eg. 1) and second Gateway 10 (Note: don't check automatic) on TCP/IP Advanced setting.
The idea is when XP find out after several retransmit that no traffic can go through the lowest cost gateway (preferred one), ie. it's down, it will failover/route the traffic through second gateway automatically.

But you have to remember it doesn't give you a fall back capability only failover.

If you like more features, eg. failover function, you have to write a script (WMI) or 3rd party.

HTH,
