In my office we have a server with Windows 2003 Server, before explaining my problem I want to tell that I am very new for this server issues, the server its self is the DNS and DHCP server. Server Admin set all the DNS Settings for us but he is not with us, and I am the one who maintains all the things related to the server for now. Getting into my issue, recently we took a new internet connection for that internet connection all the DNS Settings are different from the older one. Now I want to set all the settings according to the new connection. As of now, we are doing it manually, manually in the sense logging into each and every system with the admin user and changing the DNS Settings. Before that that admin set all the settings in the Server only, so we just have to set IP address to obtain automatically and it was worked fine. Now, we have two internet connections, one is the main and the second one is the alternate, if the main is down we will use the alternate one. For that, changing the DNS settings in all the systems whenever we change the connection is became a difficult point. My question is, I just want to set all the settings in the server itself and whenever I change the internet connection it should provide all the systems without changing the settings in all systems. How can i do that? Is the information that I gave is sufficient or do u need more information? Please let me know and help me.
Thanks in advance.
