DHCP, DNS and Linksys Router

November 8, 2008 at 05:19:03
Specs: Server 2003, P4 1 gig

I am have setup a Windows 2003 Server, and I want to setup DNS and DHCP on this server. I cant seem to get the DNS and DHCP setup correctly. I have a Linksys router and I go in there and disable the DHCP Server. I lose internet and cant seem to get everything working. Any help on this subject would be appreciated. Cant the router act like a gateway for the internet and have it all run off the server.

You need to install and setup DNS and DHCP at your server, when you plan to disable it at the router.
The server then works as a gateway between the workstation and the router.
So if a workstation tries to access a webserver on the internet, it asks your windows servers DNS for the IP address of the web server, gets the answer and asks the windows servers gateway to route the workstation to the right direction.

I guess at the moment, your workstation has an ip address of 169.255.x.x what means, that the workstation could not find any DHCP server to retrieve an IP address.

Ok I will try and get them configured. As for the DNS servers I will be using, they are the ones that my ISP has correct, or do I need to forward zone them to the DNS servers?

The workstations should be configured to use your windows servers DNS.
At the windows server you should configure the DNS server of your ISP in the forwarding tab, so that non local DNS queries are forwarded to your ISPs DNS, answers get back to your DNS server and from your server the replies are handed over to the workstation.
So no workstation always asks your DNS server and always gets the result from your DNS server.

Key here is setting up dhcp on the 2003 server. Once you authorize it it's good to go. Note your routers gateway ip like 192.168.1.1 for example.

Next document your ip plan.
Router 192.168.1.1 [static]
Server range 192.168.1.2-10 [static]
Managed switches 192.168.1.11-20 [static]
Network printers 192.168.1.21-30 [static]
Networked pcs 192.168.1.31-254 [dynamic]

So you set your dhcp to provide gateway, dns, and then the scope of the networked pcs.

Then they will have internet and MS Dns will dynamically be updated.

So my gateway would be the Router IP
Set my range of IP's
Can I include this with my network printer or do I specify like you did

Set PC networked to Dynamic so it changes all the time when they log on.

Can DHCP and DNS be configured at one time, and do I need to forward any zones

The IP addresses are assigned My Server IP is 192.168.0.1 and the first IP out is 192.168.1.10.

I went to the Network connections and added in the gateway pointing to the router. I cant get no internet.

I did succesfully join the domain, but when I try to log in with Client PC with Admin username and password. I get to where It says cant log on.
