Hi,
I am a Software Engineer and fool around with hardware, so please be patient.  I am trying to setup my Windows 2003 Server to use the DHCP server that comes with my Linksys cable router.  I have set up the Windows 2003 Server to be a primary domain controller and have given it a static IP address of 192.168.1.100.  I set the gateway to be my router address of 192.168.1.1.  It is not working.  I cannot access the internet.  What do i need to do for DHCP and DNS on my Windows 2003 Server?

Thanks,
Emidio

If you're using a static IP on the server (as you should be) then you'll also need to statically assign the DNS servers as well.  If you use DHCP, then you'd want to configure an IP reservation for the server so that it is always given the same IP address.  Personally, I prefer to use the DHCP server in Windows since it has more configurable options.

Some troubleshooting questions:
What did you put as the DNS for the Server?
Can you ping the router (ping 192.168.1.1)?
Can you access the internet using a WinXP box using DHCP without the server, in other words, are you sure you are connected with the linksys?

DHCP shouldnt be used at all on a Win 2k3 DC, it should be put in manually.
The Gateway should be the linksys, and the DNS should be itself and the linksys.

On the workstations make the DNS the server, and the ip/gateway DHCP.  Dont enable the DHCP server on the server otherwise two machines will be trying to hand out IP addresses.

Thanks guys,
I got it to work, but i had to reinstall Windows 2003 Server.  It did not seem to like the upgrade from 2000 Advanced Server.  I have one problem.  My internal domain is the same as my domain that i am having hosted by someone (ie mydomain.com is my internal domain and i also have www.mydomain.com being hosted by someone else ).  So when i try to get to my public domain name, i get the internal dns pointing me to my domain controller.  Is there any way to fix this or to get access to my public domain?

Thanks again

Put a host record in your DNS for www to point to the web server.
Also on your domain controller, you can install IIS and on the default website change it to a redirection URL, from mydomain.com ro www.mydomain.com.
