Server infrastructure question - Page 2

It sounds like you might not have dns forwarding configured properly. Follow the steps in this article:

http://www.adiscon.com/common/en/articles/configure-windows-dns-for-internet-access.php

"To view or modify the configuration, right click the server in DNS manager. Then, select "Properties" from the context menu. A new dialog appears. There, select "Forwarder":

If "Enable Forwarders" is checked, your DNS server will use the forwarders specified to resolve names it cannot resolve itself. Forwarder addresses are specified in the big listbox. In the above sample, there is a single forwarder with IP 172.16.0.1. Please note that forwarders need to be specified by IP address and not DNS name, as most probably your DNS server would not be able to resolve the IP address without using the forwarder - what would yield us to an endless loop.

In a typical setup, the DNS forwarders should be provided by your local Internet access provider. As DNS queries are cached, this will result in optimal performance. We recommend having at least two forwarders. If - as in the example - only a single forwarder is available, this is a single point of failure. If it goes down, no name resolution and thus Internet access is possible - even if the connection and all other servers are working perfectly well. Most ISPs provide at least two servers for their customers. If in doubt, ask!"

Also you want to leave your router as the default gateway, only the primary dns server should be pointing to your server.

EDIT: I can ping my server with the computer connected to the domain, and I can access the files on the RAID 1 array. The only thing I cant do, is to go on internet. But if I then change the gateway of the computer for the modem/router, I now have access to the internet but lose access to the server's storage!

If I'm understanding you right you're changing your network settings to get internet. Change the settings in IE (insert other browser) to point to the proxy address (in LAN settings in internet options)

If I don't put the server as gateway for my computer, it just doesn't want to connect to the domain. In fact, there's a window poping that says that it haven't found the domain controller on the server, and list my server name as nameofmyserver.modelofmyrouter.com instead of nameofmyserver.nameofmydomain.com ***!

You're doing something wrong then because your default gateway should be your router and your DC should only be for your DHCP and DNS (and GPOs if you're using them). If you're statically assigning IP addresses are you making sure that everything is in the same subnet?

Here is an example of how a typical small network should be configured.

Lets assume you are using the 192.168.1.0 range with a /24 subnet (255.255.255.0). Your domain controllers provide DHCP and DNS services.

Gateway/router: 192.168.1.1
Subnet: 255.255.255.0
Domain Controller 1 (DNS/DHCP): 192.168.1.10
Domain Controller 2 (optional) (DNS/DHCP): 192.168.1.20

Client:

IP: 192.168.1.100
Subnet: 255.255.255.0
Default Gateway: 192.168.1.1
DNS 1: 192.168.1.10
DNS 2: 192.168.1.20

Couple of things to check for:

On the DNS servers, make sure you have Forwarders enabled to your ISP's DNS servers or a public DNS server like Google DNS (8.8.8.8 or 8.8.4.4). Run the nslookup command on your client pc to verify addresses are resolving. i.e. nslookup google.com

Disable any DHCP or DNS services on the router.

Make sure the domain controllers are not providing any type of routing service and there is no switch that is providing any Layer 3 services either. Routing should be handled by the gateway/router.

Are you using any VLANs on your switch, servers or router (other than whatever default VLAN configuration your switch or router uses)?
