Configuring DHCP on a 2003 SBS

I have just setup a Small Business Server for a client of mine, and the Server came with only one NIC card.  I have connected the WAN connection to this NIC card and the Internet is working properly.  I went ahead and installed an additional NIC card on the Server as well.  My question is... my client wants the Server to give out the DHCP for the rest of the workstations on the network.  There are no routers on this network, and the Internet connection is a fixed static IP on the NIC card which came with the Server.  Is there a way to configure DHCP to be supplied by the additional NIC card I added, and if so... how do I do this?

I would approach it a bit differently depending on what type of connection the WAN uses.  I frequently see and have setup SBS 2003 with only one network card.  

If you do have a router which is connected to the internet, and it is this that you have connected with a Cat5 cable to the adapter on the server?

Basically, a typical setup which works could be like this:

WAN Router with IP
SBS Server with 1 network card configured to
SBS runs DHCP on its 1 and only network card, and DHCP option 003 ROUTER is set to
Clients obtain a DHCP address with server/DNS/router info and are able to connect to internet via their automatically set DHCP "Default gateway" of

Let me know if this is any help
You say you have set this up with one NIC?

When you ran set up did it tell you that there was a DHCP server already on the network?

If not and you want to run two NIC's then you should be able to run CIEW specifying the card connected to the WAN as the external card and the The card the card connected to the network switch as the internal card and this will hopefully start belting out IP's.  If not come back and I'l go through the motins of setting up DHCP.

Let me know?

I went ahead and bought another NIC card and installed it.  I configured the DSL modem to stay connected at all times, and then proceeded to configure the Internal NIC for DHCP. The Internal NIC received the static IP of the DSL line, and then I enabled the DHCP on the SBS Server on the second NIC I bought.  With that being done, I followed the Connect to the Internet wizard on the Task list, and everything worked out fine.  The Exchanger Server came up and worked on the first try....

Thanks for your help
