Has bought a new server with 2003, the old NT 4.0 domain controller should be taken out of the network. Should the win2003 server be added to the domain and be promoted to a DC, and the NT server to a BDC? Or should I just take the NT server down and make a new domain with the same name? There are not many users in this domain so making new accounts are not the problem. What I want is to make this invisible for the users, I don't want to spend time at the clients adding them to a new domain or see their local profile is getting lost. Any advice how to do this the easiest way?
