Hello all. I work in I.T. but I'm a noob. Been in the field about 6 months. We have a Windows Server 2000 system that has our active directory on it. It only has a 20 gb HD. We have another server brought up now with Server 2008 running on it. How can I take our AD forest from the Windows 2000 machine and import it into the brand new server and then just ditch the 2000 server and run off the new machine. Basically I just need to know how to get the active directory into the server 2008 so we can get rid of the old crappy system. Please help I need to do this for work bad as you can see its not good to serve your network on a 2000 server with hardly any HD or memory. Thanks alot. I appreciate it if someone helps
