Server Gateway and DNS settings

Hi,

On our network we have one w2k3 server and another
modem router for internet access. I have created static IP
address for some users. Here's a example config I used
for one machine:

IP: 10.0.0.30
subnet: 255.255.255.0
Gateaway: 10.0.0.65
preferred DNS Server: 10.0.0.75

The w2k3 server's address is 10.0.0.75
the modem router is 10.0.0.65

As you can see I assigned the gateway for user to point
to the modem router. This is correct I believe. But am
wondering should I have set the DNS server to point to
modem router as well even though the w2k3 server is a DNS
server?

Thanks,
Pete

Pete,

The internal clients should point to the internal DNS Server for DNS name resolution. The configuration above looks good. What you can do next is set
the internal DNS Server to forward to your ISP. I am assuming that this is an Active Directory environment and the only way that this will work is if the DNS
Server only points to itself and all clients of the AD point to the AD DNS Server for DNS.

The DNS Server can then be configured with a forwarder.

Here is an article that describes how to configure the DNS forwarder and a few other helpful DNS Articles:

Ok there is one catch that I didn't mention to this
network arch. On the w2k3 server we have another internet
connection using satellite. The reason why we did this is
to alleviate the traffic to the satellite and balance out
the network for proformance reasons. So not sure I could
setup forwarders for modem router?

Thanks,

Pete

Pete,

So the Windows Server 2003 has three interfaces? One for the LAN, One for the Satellite and one for the Modem? WOW! This would present a situation
where the server would have multiple default gateways and a very bad idea as Windows only supports a Weak ES model of routing. (1 routing table per
system)

Can you clarify the configuration for me?
