    My setup is as follows -

    Internet Router <---> Server Nic1 <->(Server 2k8)<-> Server Nic2 <----> Switch <----> Clients

    Internet Router Ip = 192.168.1.1
    Server NIC1 = Obtain IP Automaticlaly

    Server NIC 2 = 192.168.0.1, subnet = 255.255.255.0, Gateway= 192.168.1.1, DNS = 192.168.0.1
    Client = Obtain IP automatically


    I am able to obtain IP addresses through the DHCP server for my clients and I am able to browse internet on the server 2k8, however the clients are unable to browse the internet.

    Any ideas what may be the issue?

    Thanks

    Did you install anything like RRAS (or whatever it's called now) to let IP traffic be routed and NAT/PAT'd though the server?

    I didn't. What NIC do I need to install it for and what settings do I need to apply?

    I'm not sure of the specifics required for Win2K8 and don't have time to look now, but no OS is a router by default (except ones like IOS on routers, of course) so you need to figure out what they call that package in Win2K8 now and install that.

    Install routing and remote access on the server. With devices on different network segments, you will need a router to talk between the different networks. You already have 2 NICs installed in the server, that is what you need for RRAS to work.

    Is there no way to do this without a router?
    I thought within server 2k8 there was an option to route or share the internet?

    What is the step by step instructions to install/configure to share the internet?

    RRAS (if that's what it's called in Win2K8) will make Windows a router. However, Windows doesn't really deal with being multi-homed very well so be prepared for things to act up if you want that server to do more than just route.

    I would need to find it but MS specifically says not to use RRAS on domain controllers. [and then does it in SBS but yeah]

    Yea, unless you have some extreme compelling reason to do this, its not recommended.
    I'd be curious as to why you want to do this.

    As stated, you need to install RRAS on the server.

    MS says not to do a lot of things that they do with SBS. I believe the primary thing to look out for is DNS registration so that hosts on one side don't end up resolving the address for the other NIC.

    I wouldn't be surprised. There is certainly a lot of powershell buried in SBS. That is how I would have done it personally also.
