Replacing 2000 DC, best way

I want to replace our existing 2000 DC with a new Dell server.    I can make that server either 2000 or 2003, I eventually want to make it 2003 but didn't know if it would be easier to add it as a 2000 server and make it a DC along with the current 2000 DC and then upgrade the new server to 2003.   The reason, I was thinking this was to keep the current 2000 DC just the way it is if I had to back out of the upgade.   What would be the best way to do this.   I have read several post to just add the new server as a 2003 member server and then I am a little confused as to where to go from there.  I am a little familiar with this but am not a server person by any means, more on the networkng side of things.   We have previously tried to upgrade the existing 2000 DC to 2003 and it crapped out in the middle of the install and got into a reboot loop.  We had to wipe the DC and start from scratch and restore everything from a backup.  We are looking to avoid this issue completely by using a new server.

I would have the new 2003 server and copy over the domain structure, then turn off the 2000 server and escalate the 2003 to native mode.

without sounding to stupid, how do I go about doing that?

I disagree - a native mode 2003 domain is not all that important to most small businesses at this point and having a second domain controller would provide a level of redundancy.  So I'd keep the 2000 server.

You would add the 2003 as a member server just like you add any other system to the network.  THEN, you need to start the process of upgrading to a 2003 Active Directory Domain (this does NOT necessarily involve upgrading the 2000 server, but by adding a 2003 DC, you ARE upgrading the DOMAIN).  

I have several links for helping you do this - just note, some of them may not apply if you choose to keep the 2000 server as a 2000 server and not upgrade it (which is fine).

Quote from the top of this article: "Several glossy Microsoft presenters have stated that all you need to do to complete a Windows 2003 Domain upgrade is run ADPREP and then upgrade away.  This may work for very small / simple environments but it is definitely not good advice for most companies.  After upgrading five servers in two unrelated domains and installing many fresh copies of 2003 I can say that I personally would not skip a single step in the process I have developed below."
