Dual Gateways

My server is connected to two ISPs on different NICs. I have noticed that if
I ping the IP of the ISP it receive the packets and sends back the data out
to the other NIC. Is it possible to put a static route or something that
everytime a packet is received on the NIC, the NIC that received the packet
will send back the data using the NIC that received the packet.

No. The inbound packet and the outbound packet are two entirely separate
communication sessions. The routes are determined independently for each.

So does this mean that there is no way to do this using the built-in features
of Windows Server 2003 except if there is an aid of a certain router or
special software?

Even typical routers won't do it. It is the way TCP/IP works,..it isn't
Windows and it isn't routers. However there is software that can deal with
certain things in certain situations.

Check out RainConnect or some of the other solutions by www.rainfinity.com ,
but I can't say that you will find anything.

If it is a Cable or DSL Connection there are some Cable/DSL NAT devices that
have two WAN ports and can do certian types of "load balancing" between the
two links. I do not know of any exact models, but I do believe some of the
Linksys proucts can do that. But that is not what you are exactly asking for
either.

I also believe ISA Server can do this, but only in certain "Server
Publishing" stiuations. For example, if the ISA has multiple external IP#s
and it is being used to Publish an internal FTP Server on a certain external
address,...it will keep the FTP traffic on the proper IP# in both direction.
It required ISA2000 SP1 or newer. But I don't think that is a
solution,...it only works like that in certain situations.

The best thing to do is to not create a situation where it matters which
outbound path it takes.

Ask your ISPs if they want to establish a tunnel communication with you
