I have a network (server client) the server is Windows Server 2003. I installed Root DNS & DHCP on it. All clients are Windows XP SP2. This network connects with the Internet through an ADSL router.
My problem is with Microsoft Outlook for clients. I couldn't send or receive any message when the primary DNS of clients is the DNS of my LAN and the secondary is the DNS of the ISP.
But when I invert the primary with the secondary, then I could send and receive messages, but log on to the network takes a long time. The Internet is working in both states. Please tell me what I can do for this problem. Thank you.
