We are still running Windows NT as our server. We are thinking of, moving to windows 2003 servers. Our setup is we have small group of users in different countries, none of this offices are connected each other. Every office have there own NT server, (as their own domain). All this office has a circuit coming to one of our main router that provides them the internet access. All the users on the particular office logging to that server, In Washington, Dc our HO we have a large network, with Novell, Microsoft etc. We would like to keep the settings as it is, but we want to replace the NT servers with Windows 2003 servers. I installed a 2003 server and playing with that, by going through the Microsoft my understanding is that, Without installing active directory, the users will not able to login to the 2003 server. I am kind of confused, I would like to know is it possible to have a 2003 server installed, the same way we are using the NT server. Do we need to have the active directory activated?
