I want to setup a DHCP and DNS servers on Windows Server 2003.
The DHCP is working now, the DNS is only half working -

From the server, I can access the internet everything is good.
From the clients, I can access the server (LAN), but cannot access web pages from the internet. When I do ping from the clients, it's giving weird response - if i do ping to Google from the clients, it's writing ping Google (208.x.x.x), meaning it's resolving the ip of all websites, but then the next lines are request timed out.
if from the clients i do nslookup it's working well...

the LAN is 10.0.0.x, and the server has only 1 network adapter, so I configured 2 IPs on this adapter - main one is 10.0.0.10 and second one is the IP of internet (we have here a static ip on the internet, so I wrote it down).

in the server, in its network configuration - as dns server i wrote itself - 10.0.0.10, as gateway I wrote the gateway as the ISP gave me 82.x.x.x, and it has two IPs.
In the server's dns service, I wrote that the dns forwarders are what the ISP told me 193.x.x.x.

From the clients I cannot ping the router which is 82.x.x.x but I can ping successfully both the IPs of the server - 82.x.x.x and 10.0.0.0

Thanks and have a wonderful day full of light,
Yoav

I tried to put on the server, the DNS server as the one I received from ISP (both in the server's network connections, and in the dhcp/dns server configurations) and it's not working. Anyway, when in the server I write itself as DNS server in its network connections, the server can contact the internet well. In the DHCP configuration, if I write the Dns Server as the server itself (10.0.0.10), then happening what I wrote above, resolving the DNS but no ping. When I write as DNS server, the DNS I got from the ISP, then it's not even resolving, just writing "ping request could not find host...".
In the DHCP configuration, there are the "Server Options", so there whatever I write as DNS servers doesn't matter to it.

I am pinging google, from the server it's working well, from the clients it's resolving the IP (writing Pinging www.l.google.com [209.85.137.147] with 32 bytes of data) but then the next lines are "Request Timed out".

Also when I try from the clients to ping the gateway (the modem itself which is 82.x.x.1) they cannot (of course for the server it's working).

I suppose something with gateway configuration is not well.

thanks a lot
