I wanted to field this question out to those who might have done this before. I have a Windows Server 2003 install that was the initial domain controller for a given domain. It has a second 2003 Server that is also a domain controller. A couple of weeks ago, the DC, we'll call it 01, had some kind of hardware failure that either has to do with the RAID controller or the drives, or possibly something else. Whatever the problem, I can't get it to boot and I'm pretty sure it is not recoverable. I put a new disk in it and I want to try re-installing Windows 2003 on it and adding it to the domain so that it is again a failover pair of Domain Controllers. If the hardware will not allow me to do that, I will use different hardware. I want to know what the recommended practice is for this procedure and what might be the possible dangers.
