Hi I have a DC on windows 2000 and I would like to upgrade to windows 2003. But I have no idea how to do that, I was  never done that before, to avoid screwups I recreate my DC on a virtual machine so I can made the process on experimental environment first and learn the right way to do that. Then backup all my data and do it on the real one.

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."
