I´ve recently installed a win server2003 with the DC role. The scenario i have is a server that is a DNS with AD connected with other pc that were recently added to the newly created local domain. the gateway is a router (also modem) that has a WAn setting to get the configuration using the ISP DHCP. internally it is the dhcp for the LAN. I´ve been experiencing a lot of problems trying to add the computer to the domain, i have to set the PCs NIC configurations to manual and remove the gateway and put the DC IP as primary DNS to be able to get access to the domain. After that i need internet and the PCs only get to the internet configuring the secondary DNS with the gateway IP and put the gateway IP back to the NIC settings. Once all that is done i have troubles communicating with the internal DNS, it takes a long time to open a network drive, users take long to be able to log in to their session. It seems like the gateway is sending the name resolutions to the external DNS and making the LAN very slow. It is the first time i have this issues, i´ve also configured forwarders on my DNS. Can someone help with thi issue?
