I have a small network and would like confirmation or suggestions on how to
configure my 2003 SBS. It is up and running but I am getting some lockups.
Right now the server is getting DHCP from the router and so are the network
computers. DNS and the Default gateway are also pointing to the router.
Should I:
- Set a static IP address for the server's LAN network card.
- Setup DHCP om the SBS to provide IP adresses to the clients
- Ensure the server is running DNS and have the server point to itself for DNS
- Have the WAN network card on the server get DHCP from the router for
internet access
- Would the default gateway point at the router IP?
- Would I need to configure forwarders in DNS?
- Configure the LAN network card and WAN network card in the server to be on
separate subnets?
- If I do all of this will the clients be able to get to the internet?

Hi Pat, basically yes to everything you say!!
Your sbs server absolutly must have a static ip on every Nic. It is also
best practice to have the sevrer running dhcp and dns and using itself for
dns resolution. You dont necessarily need 2 nic's in the server. I prefer
just having a LAN card in the sevrver and using the router as the gateway for
the clients and the server (this router must also perform the firewall
function. Clients should use the sbs server for dns especially if they are
part of the sbs2008 domain (this is a must). If your router is configured
correctly clients will then be able to access the internet.
If you do have 2 nic's in the server they should be seperate subnets though.
one lan and on wan.
Good luck sounds like you have alot to do

James,
Thanks for the reply. I did all of that stuff and I think the LAN is much
more stable now, no lockups so far. However none of the workstations can
access the internet but the server can. DHCP and DNS are setup and I know
DHCP is working.
I am OK with just using one NIC as you suggest and I have seen some other
suggestions to do that.
I'll take a couple more stabs at getting it to work with 2 NICs 1st.
So I should set the gateway IP on the WAN NIC and that gateway should be the
IP address of the internal side of the router? There should be no gateway IP
on the LAN NIC. For DNS I have both the LAN and the WAN NICs configured to
point to the internal server's DNS, which is the IP of the LAN NIC.
That is how it is now setup but the network clients still can't access the
internet. Do I have to install and configure ISA server for this to work? Any
suggestions are appreciated. Otherwise I will just use the "Change Server IP"
option in SBS and disable the WAN NIC. Thanks,

Bear in mind that just having 2 nics in the server will not make it act as a
router, you need Ruting and Remote Access installedn and configured.
If your server can access the internet then i bet setting the gateway on the
clients as the router will work. In your dhcp scope is the gateway assigned
to clients the IP of the router???
Try assigning a client a static ip/gateway/dns server and see what happens
then.

It appears routing and remtoe access is all setup. It doesn't like it if I
have the default gateway on a different subnet. I am going to disable one of
the NICs and have everything on the same subnet. Thanks,

No you cant have a gateway on a different subnet, the whole point of a
gateway is that its a way out of the hosts subnet it would be a contradiction
if it were on a different subnet.
If you want to use your sbs server in this way the gateway on the clients
needs to be the internal/lan nic in the server (on the same ip as the
clients) and routing configured appropriately.

The LAN NIC is 192.168.16.1, the WAN NIC is 192.168.45.10, the LAN side of
the router is 192.168.45.1.
The SBS server is doing DHCP for the clients and the scope is 192.168.16.2
thru 200. The default gateway for these clients is the servers LAN IP of
192.168.16.1 and this is also the DNS server.
On the WAN NIC I assigned 192.168.16.1 as the DNS server with a default
gateway of 192.168.45.1.
