Problem with multihomed computer with disjoint network

Guest

Hello!

We have a Windows 2000 Server with 2 NICs, each connected to a
different network.
The reason that we have 2 NICs is that we run 2 different web sites on
a single server.
The problem is that sometimes the server is not responding.
A guy from MS answered my post saying that it's related to our server
configuration.

My question is how do I configure my server.

Here's a brief description of the server.

Windows 2k Server
NIC1 (192.168.0.2) <----> DLink Router (192.168.0.1 & Public
IP)
NIC2 (192.168.1.2) <----> Linksys Router (192.168.1.1 &
Public IP)

The 2 routers are in a same network in terms of public IPs.

Here's "Route Print".

Default Gateway: 192.168.0.1
===========================================================================
Persistent Routes:
None

As you see, the Default Gateway is 192.168.0.1 which is more important
for us.
If I change it to 192.168.1.1, then the problem gets worse.
However, even if the Default Gateway is 192.168.0.1, it sometimes
doens't respond to requests from outside.

I read a good doc from microsoft and I understand that my current
configuration may be a problem.
But I don't know how to fix it.

I have another theoretical question.
If a computer has 2 NICs like our server.
If it receives a request thru NIC1, does it always respond thru NIC1 or
may it respond thru NIC2?

I've been fighting this issue for 3 days now and am very frustrated.
Please help me.
