Greetings to all you out there! I must thanks you all for the great job you are doing sorting out issues posted.

Scenario

I am connected to the Internet via a DSL link. The DSL box in my office routes and dynamically assign IP addresses to the clients on my network?s clients.

ISP configuration to client (Assigned using DHCP)

IP: 10.0.0.1-254
Subnet: 255.255.255.0
GW: 10.0.0.138 (DSL router box at my end)

Pri DNS: 83.143.0.249
Sec DNS: 83.143.0.246

Recently, we installed an Internal DNS that was promoted to a DC. The following TCP/IP configuration was applied on the internal dns

IP: 10.0.0.8
Subnet: 255.255.255.0
GW: 10.0.0.138

Pri. DNS: 10.0.0.8
Sec. DNS: 83.143.0.246

On the domain created, I configured forwarder to the IP address 83.143.0.246 so that external query will be forwarded to the ISP?s dns servers.

Now, when I login to the created domain, and try to browse on the Internet from a client machine, the connection failed.

The client configuration is:

IP: 10.0.0.7
Subnet: 255.255.255.0
GW: 10.0.0.138
Pri. DNS: 10.0.0.8
Sec. DNS: 83.143.0.246

I want information on what I need to do to make this work.

Secondly, i want to know if i can setup DHCP on my server. That is, will it conflict with the one already running thru the provision of the ISP's router.

On the client machine\s go to TCP\IP properties , goto advance, goto DNS check "Append these DNS suffixes (In order)" put in your DNS full name such as "microsoft.com" (and any other DNS that you have if you have more configured for example I have one on my router and one on my DC) at the top window put in the DC and the router address as the DNS server to use and you should be OK.
As for the 2nd Q you will need to decide which DHCP you will want to use as you cannot have 2 running on the same network (Unless they are in different subnets) but I don't see any problem runinng DHCP from you DC.

What is it?
This would be the next hop. Is it the DSL router or a firewall?

If it's the server then the server must have routing to forward requests the the firewall / DSL.

SORRY IT MIGHT SOUND FOLISH... I WANT TO KNOW IF IT IS WRONG TO PUT THE DEFAULT GATE WAY ON CLIENTS' PC. IF YES, SHOULD IT BE OMITTED? ON THE 2Q, THE DSL IS A ROUTER.

THANKS FOR YOUR RESPONSE.

No routing, clients are restricted to the subnet they are on.

So You need the Defaulr Gateway to be the Router (if on same subnet)
