I have my domain controller setup on an old Dell PowerEdge 1400 which is about to break down anytime. So i would like to find out, how can i setup a new domain controller (on a new machine) to replace the old one in the existing network without having to reassign every users(100 users) on the domain again.

these briefly steps apply only to win2k servers and win2k3 servers:

(1)after installation the window server on the new machine (recommended same version of windows server), Promo the server to new DC using command DC Promo).

(2) the wizard will ask you if this DC is in new forest or new domain or it is on existing domain, you will take on existing domain.

(3)after promoted the new machine to a new DC, and in order to remove the old one you have to run the command DCPROMO at the old DC as right way to transfer all the FSMO and GC to the new DC.

note: my answer is very short i hope it is useful for you

I'd make sure to back-up your active directory before you start demoting your domain controller...
