I just installed a Domain in my W2k3 server system, upgrading from workgroup. My sql guru mentioned I should have two network connections on myh server. One for the "in-house" network, and one for the connection to the internet. Then he said it wasnt necessary. we were pressed for time. The server has two built in nics. When we upgraded the system from workgroup to domain we now have the dhcp being provided by the server, and it handles the dns as well. we disabled the dhcp on the router. It seems now that I many not even need the router, if i plug one server nic into the cable modem, and the other into the switch that all the workstations are plugged into. How would the experts advise to set this up?
