Added 2nd NIC to access the Internet, Now having trouble.

We have a win 2003 sever origanally with 2 NICs. One to private 192.168.0.0
and the other to the Internet (DSL) Then we added a third NIC for a HS
Internet. We will remove the DSL at a latter time after to which the mail MX
records. But for now I need both INTERNET nics to work. I ran the Routing &
Remote Access wizard to reconfig the new NIC for NAT. It looks correct but
this is what is happening. If I have the default Gateway listed on the old
DSL NIC, uses lose there connection to the Internet but can recive e-mail
threw that NIC. If I disable the DG on the OLD NIC then no one gets any
e-mail but the Internet works fine. I noticed that when I have a DG listed
on the OLD NIC I get two 0.0.0.0 enties on the routing table. I think it has
something to do with two 0.0.0.0 enties but am unsure how to fix.

Not sure what this means: "We will remove the DSL at a latter time after to
which the mail MX records." But, if you get e-mail from a public IP mail
server; delete the default gateway on the DSL NIC and configure a static
route:

route -p add <IPaddressofMailServer> mask 255.255.255.255
<IPaddressofDSLdefaultGateway>

No matter how many default gateways you configure, Windows will only use one
of them unless and until it fails.

You can't do that.
The cut-over has to be immediate and all-at-once.

Put everything back the way it was, uninstall the third Nic (first) and pull
it out of the machine (second), in that order.
Switch the new DSL line to the original external Nic when it is time to
switch.

It only takes a couple minutes to do. Do it during low use time and most
will never even know it happend.
