All firewalls are disabled, dns works, client resolves to server and vice versa, nslookup and ping. Eventhough AD, DNS, DHCP and SCE are all running on the same server. When I open the console, by default its sees the itself under computers and All servers section but with an error under the health state. The only thing that is since its on a isolated network, there is no internet access. ( no real gateway) would that matter?
