hi guys,
Could some one please help me,

I'm running 2 severs, 1 has SBS2008 (domain controller) and the other 2008 standard ( apps, and terminal server), my dc has 2 nics one for the lan and the other for internet, apps has one nic

the problem i'm facing is that on my dc i have internet connectivety but on my apps and client computers not. the preffered dns is and i've tried, and as default gateways but it just doesn't work.

this is my 1st 2008 network and i really don't know what else to try.

Any ideas?

    Hello alphanetworks,

    why are you using 2 nic's in the SBS?
    SBS 2008 does NOT support 2 nics.
    please read the sbs info here:

    so remove the nic, add a separate firewall device and run the wizards again.

    I understand that your router is plugged to the network.
    Therefor all workstations and app server should have:
    Ip address : network

    then try pinging it does not work - You need to configure Routing and Remote Access service on the SBS2008

     if it works try
    pinging if it does - all ok
    if not configure DNS server service on your SBS2008

    btw, when you removed the NIC you need to run the wizards in the SBS console to get your internet access back to work.
    The ONLY dns server is the SBS server, which uses root hints to connect to the internet (although you COULD add your isp dns servers as forwarders in the dns server properties of internet connectivity might be unstable).
    So the clients, and other servers in the network only point to the SBS as their ONLY dns server.

    Read all the SBS 2008 docs i've provided you, they will be very interesting.
