How to configure router windows 2003(SBS) DHCP, DNS for internet connection on client computers

hello friends,

i have windows 2k3(sbs) having 3 network cards, with one netgear switch is connected and to the switch 12 client pcs win xp and win 2k with latest service packs. win 2k3 sbs is running as domain controller, DHCP activated, WINS running.
I have DSL Connection - modem connected to NetGear FVS 318 router.
DSL connection is with dynamic ip.

Windows 2003 SBS (192.168.100.1, 255.255.255.0) - Switch - Client computers

i dont want to use RRAS, but simply want to share internet through router, but want to run DHCP from Windows 2k3 SBS.
I have diabled DHCP on router.
Added Router ip address (192.168.100.201,255.255.255.0)     now i dont know what would be the DNS address of router. Gateway of router.

can some body tell me how i connect these things using 1 and/or 2 Network cards of server that local network and internet sharing both can work.

please write me what addresses should i give as ip, subnet, dns, gateway, dhcp fields in server/router where ever needed and DNS forwarding in server to which address?

little confused ...

Give your Router a Local Address of 192.168.100.2 (or an open IP)
You would Setup DHCP on your 2003 server.

Give them a Scope of "192.168.100.50 - 192.168.100.200"  or something similar.
Subnet would be 255.255.255.0
Gateway would be 192.168.100.2 (your Router)
DNS would be 192.168.100.1 (your Server)

Setup your DNS Server on your win 2003 server to forward to your ISP's DNS Servers

Sorry I didnt read that your router had a address of 192.168.100.201.  Change my address of 192.168.100.2 to 192.168.100.201


<"Added Router ip address (192.168.100.201,255.255.255.0)     now i dont know what would be the DNS address of router. Gateway of router.">

The WAN Settings would be what your ISP gave you for settings (IP, Subnet, Gateway, DNS)
The Lan settings would only need the local IP (192.168.100.201/255.255.255.0)

Thank you 2hype for your replies it cleared some things..now i have something to ask where i am not very clear...
I have dynamic IP for DSL from my ISP. then what addresses should i give in DNS forwarder? and should i also give WINS address in DHCP scope? well asking you more in detail because i am not on server i have to do it tomorrow morning.
And as i have given router details under - DHCP - router(double click) and then i had filled ip address there is that okay?
And as i do so then i dont need second NIC right. Server would get internet access on same LAN Cable that is Connected to switch?
waiting for your reply...

For the DNS Forwarder you should input your ISP's DNS.  Give them a phone call and they should tell you there Primary and Secondary DNS Servers.  If they dont Puting your Routers IPAddress for the DNS Forwarder should work as well.

<"and should i also give WINS address in DHCP scope">

If you have a wins server installed on your network you would create a entry in the DHCP
   You would add a 044 WINS/NBNS Servers Entry with your Wins Server IP Address

<"And as i have given router details under - DHCP - router(double click) and then i had filled ip address there is that okay?">

That is correct.

<"And as i do so then i dont need second NIC right. Server would get internet access on same LAN Cable that is Connected to switch?">

You Do not need a second NIC.  For your server NIC your Address should be.  This will get you internet Fine.

IP 192.168.100.1
Subnet 255.255.255.0
Gateway 192.168.100.201
DNS: 192.168.100.1

Hi  2hype...
we had this same discussion going on as i didnt know where should i put my original question when i asked to EE...so in other section(Windows Server 2003)... i got this reply regarding DNS Forwarding address...

//..... If they dont Puting your Routers IPAddress for the DNS Forwarder should work as well....//

-----User: mikeleebrla
Your router isn't a DNS server, so if you tell your DNS server to use your router as a DNS forwarder you will have all sorts of problems since it can't answer DNS queries.  You don't have to use YOUR isp's DNS server, you can use any public DNS server.  A few are listed below:


ns1.yahoo.com 66.218.71.63
ns2.yahoo.com 66.163.169.170
ns3.yahoo.com 217.12.4.104
ns1.msft.net  207.46.245.230
ns2.msft.net  64.4.25.30------

now i am little confused can you please check it out and tell...

Thanks...

Mikeleebrla is right you can set your forwarders up to point to any public DNS Servers and it will work fine.

I would use my ISP's DNS Server Personally.  A quick phone call and you to your ISP and you will have your IP Addresses.

If you dont want to phone you can just remove the router and plug a computer into the modem.  Your ISP will assign the computer a IP Address.  Go to the Command Line and Type IPCONFIG /ALL and write down what your ISP assigned you for primary and secondary DNS Servers.  Enter these IP Address's into your forwarder tab.

I also wouldn't set it to forward to the router. Setting it to point to the router should work though, the router will forward the request to the DNS Server it recived from your ISP through DHCP.
