Two NICS in a windows 2003 server.. Can you have two seperate Networks?

I have a Windows 2003 server, its the domain controller
and originally had only 1 NIC. Heres the situation.

On an old Novell server we had an FTP running, and a
bunch of stores could dial in to a 1-800 number which
directs to a Cisco AS5200 router here in office, which
gives the modem user a internal IP out of a certain
range, which is specifies in the cisco. We have to move
the FTP to the windows 2003 server but want to keep the
networks seperate between the FTP traffic and the other
network of our domain controller.

So we installed a second 3com NIC into the Windows 2003
server and set the internal IP on it to the same that was
on the Novel Server because the Cisco router points to
that IP. The FTP is also set to run off this IP as well
and not the IP of the First NIC. We left the Default
gateway blank at first. When we dialed into the 1-800 #
we couldnt get access to the FTP or ping the 2nd NICs IP
from our remote location, but we were on the router
because we had an IP from the routers IP Scope.

Then I remembered you need a default gateway set on the
Second NIC, which has to be the IP of the Router
Interface it is connected to.

As soon as I did that I get the error:
'Warning - Multiple default gateways are intended to
provide redundancy to a single network(such as an
intranet or internet). They will not fumction properly
when the gateways are on two separate, disjoint networks
(such as one on your intranet and one on the internet).
Do you want to save this configuration?'

Im getting this because the two gateways on the NICS are
differnet, which they have to be.

When I click yes, All my internet traffice basically
stops in the office( Which is running on the 1st NIC),
but when I dial into the 1-800 #, i can get access to the
FTP because that second NIC knows to look at the routers
IP interface.

I want to keep the networks seperate.

So is there a way I can do this?

Sure, add a persistent route to your routing table.
From a command prompt type route print /? for help.
You will be adding something like:

route -p add 10.10.0.0 mask 255.255.255.0 10.10.10.254 where the network ID
is the subnet you need to route to.

No they don't nor should they be.

DG is set to the internet NIC, for any traffic to a network that's not
logically local and only connected to the other network card, you'll
need to define a route.
