Please note the recommended DNS setup is noted in this KB article: Frequently asked questions about Windows 2000 DNS and Windows Server 2003 DNS

Additional Setup

a. Right click My Network Places...Properties. Right click on Internal NIC. Under the General tab, you should have the following checked:

Microsoft Client for Networks
QoS Packet Scheduler
File and Printer Sharing
Internal Protocol (TCP/IP)

b. Right click My Network Places...Properties. Right click on External NIC. Under the General tab, you should have the following checked: Internal Protocol (TCP/IP) - nothing else.

Right click My Network Places...Properties. Highlight the Internal NIC. Then select Advanced...Advanced Settings from the top menu for that window. This will check the bindings.

The Internal NIC should be displayed first followed by the External NIC. If not, move the Internal NIC to the top of the list.
The Internal NIC should have File and Printer Sharing bound (checkmarked) to the TCP/IP Protocol.
The Internal NIC should have Client for Microsoft Networks bound (checkmarked) to the TCP/IP Protocol.
The External NIC should be bound to TCP/IP only (no other protocols or services).

c. DHCP setup. Click on Start...Administrative Tools...DHCP.

Address Pool: 192.168.16.0 to 192.168.16.254
Scope Options:
003 Router 192.168.16.2
006 DNS Servers 192.168.16.2
015 DNS Domain Name yourcompany.local
044 WINS/NBNS Servers 192.168.16.2
046 WINS/NBT Node Type 0x8

[Please note - in official release notes, this value is usually seen as 0x1 (type B), however 0x8 is recommended for a SBS server.]

d. Internet Connection Wizard (ICW)

Start the SBS Admin Console and run the ICW.
When prompted: Select Broadband Connection.
When prompted: Select External NIC.
When prompted: Use the DNS Nameservers from your ISP as DNS Forwarders.

Check to make sure the External NIC IP address is not included in the LAT range.

SBS Console | Internet Security and Acceleration Server 2000 | Servers and Arrays | | Network Configuration | Local Address Table (LAT) Example: If the external NIC has an IP address of 192.168.1.2 and the Internal NIC has an IP address of 192.168.16.2, then the range in the LAT should be 192.168.16.0 to 192.168.16.255 (which excludes the external NIC).

Please note: While the suggested IP addressing schema of the SBS 2000 is 192.168.16.x, you can utilitize any private IP address as recommended. Thus if you have a prior set up of 10.0.0.x, you may use that as well. When attaching Win98, or WinME computers, you may need to use hosts and lmhosts files to assist them in attaching to the network.

This is the only site I have found that clearly states the parameters for setting up a simple Windows webserver on a small network. Question: will the client computers on the LAN have access to the Intenet through the router? if not, what topology would be required to have all the above with 1 router, 1 DSL line? Thank you!!!

This is the site for SBS'ers, thank you so much for making it plain and simply for us new SBS wantabes... Should I let my Linksys WRT54G 802.11g router continue to issue NAT IP's? I have 2 wireless XP Boxs that will not be on my SBS Domain. I want to leave them on my SOHO workgroup which gets its IPs from the Linksys router. Do you have any more diagrams like this for my setup. My SBS Domain is for testing only at this time untill I think I am ready to set it up LIVE for my Company Office enviroment. My Test network has 3 XP Pro SP-2 Boxs, 1 W2K Pro Laptop, 1 W2K File Server. Any suggestions would be great, Thanks again.

I currently have a small network setup in this fashion using this guide and so far all has been great. Let me say thanks for that. But I would like to know if it's possible to route internet traffic (most specifically the usage logs) through our Linksys router. The management has a tendancy to check them to view usage and teaching an old dog new tricks isn't on anyone's To-Do list. Is this possible to retain the full functions of the DNS of our server but still route traffic through the router? If not, is there an easy way to check Internet usage logs from the SBS? Preferably through a real time web interface. It would be a great help to me. Thanks!

I now use the following topology: The Netopia Router handles DHCP and attaches to my hub. My server attaches to the hub, and has a pinhole so that the static address of my router passes through to it directly. I run Windows IIS on the server and have access to my corporate website and DB over the internet with PW protection.

Simplicity is a gorgeous thing but:
The Internal NIC should be displayed first followed by the External NIC. If not, move the Internal NIC to the top of the list.

How do I do this?

Hi. Will this setup work if you do not have ISA (SBS Standard Edition) and don't have a network switch only a router?
