The section of the wikipage that refers to using powershell was a added 
by a person called Garming, perhaps he could tell us how this is 
supposed to work.
As far as I am aware, the problem is that Windows 2k used a very 
different AD dns structure, there wasn't a forest zone. This leads me to 
believe that just exporting the dns records will not be enough, you will 
very probably need to create the '_msdcs' subdomain.
