Unable to access Internet from a Dual NIC XP setup

[mickboyle]

It's 4.22am here in TO and I am unable to sleep as I
cannot stop thinking about a problem that I was working on
yesterday at a clients.

Essentially they already have a P2P small business network
and I have setup a standalone (DSL) Internet PC - Internet
Lake Simcoe.

They now want one other PC (on the existing network)
running XP to have access to this high speed service.

I tried my (Dlink Extreme G) router and wireless PCI card
and was unable to get this new unit to connect to my
router (Cordless Phone) so decided to run a Cat 5 cable
instead. I then installed a 2nd NIC on this PC to connect
the cable to.

When I type in the gateway IP (192.168.0.1) in this PCs
browser I can get to the Router Menu so IE6 is working OK
but I cannot seem to get to the outside world with any
regular www addresses.

The existing P2P NIC has a static address and the new NIC
has been left with it's default DHCP settings.

Do you think that this is some kind of DNS issue, is their
a problem trying to run 2 NICs in one XP system (and can
their Internet streams be isolated i.e seperated) or do
both NICS have to be set to the same static IP address
(can this be done?)

I should have tried my own laptop on this new NIC cable
connection but unfortunately neglected to do so.

I was rather "Snow Blind" after spending 5 hours on this
issue yesterday.

Any help would be appreciated as I have to get them up and
running ASAP today.

Thanks for your help

Mick

Simply make your subnets different. Keep your existing sunnet for the LAN.
Change the subnet for those connected to the router. Don't forget the
change the Router LAN setting, too.
