Server 2000 to Server 2003R2 - Adprep error

I am attempting to bring a Windows 2003R2 server into a Server 2000 environment.  Ultimately the goal is to remove the existing 2000 server, replacing it with the 2003R2 box.

I have begun the process by running the necessary (afaik) adprep /forest and adprep /domain command lines with no errors.  However, I am still getting told when I run dcpromo on the 2003R2 box that it is incompatible and exits.

In searching around on this problem, I'm seeing some answers that it is not possible to go from 2000 -> R2 without first going 2000 -> 2003 -> 2003R2.  Is this true (God I hope not)?

If it is not true, and you should be able to go straight from 2000 -> 2003R2 environment, any suggestions on what I'm leaving out?

It should be possible but you need to use the adprep located on disk2 in \CMPNENTS\R2\

Patently false.  My_Username's solution is correct - you need to run adprep from Disc 2.  (This is a common issue when upgrading to R2.)
