add 2003 R2 DC to domain

I previously asked this question and KTCS gave me an answer.  I ran into a snag, and was not sure how to re-open the question, so I am repeating it here.  I want to add a new 2003 Std R2 DC to a domain, and eventually demote the existing 2000 DC.

Here is what KTCS told me:
One or two little steps missing - like Adprep
Install Windows 2003 on the new machine
Assign the new computer an IP address and subnet mask on the existing network
Make sure that the preferred DNS server on new machine points to the existing DNS Server on the Domain (normally the existing domain controller)
Join the new machine to the existing domain as a member server
If the new Windows 2003 server is the  R2  version and the existing set-up is not then you need to run Adprep  from CD2 of the R2 disks on the existing Domain controller. Adprep is in the \CMPNENTS\R2\ folder on CD2. If its the standard Windows 2003 then adprep in in the i386 folder
Place the 2003 CD in the Win 2003 DC and run
Adprep /forestprep
Adprep /domainprep
this will  update the schema to Windows 2003
Now back to the 2003 machine - from the command line promote the new machine to a domain controller with the DCPROMO command from the command line Select  Additional Domain Controller in an existing Domain
Once Active Directory is installed then to make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand ,Sites, Default first site and Servers. Right click on the new server and select properties and tick the  Global Catalog  checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership)
Install DNS on the new server. Assuming that you were using Active Directory Integrated DNS on the first Domain Controller, DNS will automatically replicate to the new domain controller along with Active Directory.
Don t forget to set the default gateway (router) and DNS Servers. Talking of which all the clients (and the domain controllers themselves) need to have their Preferred DNS server set to the new domain controller
Next move the FSMO roles to the new DC as described in
Now switch off the old DC and make sure it all still works.
Once you are happy then you can demote the Old DC by running DCPROMO to remove Active Directory

But I get the following error message after tryihgn to run ADPREP on the Windows 2000 machine, using CD2 of the R2 disks:

D:\CMPNENT\R2\ADPREP.EXE is not a valid Win32 application.

Please help!

Doh!  In my haste, I grabbed the 64bit cd!
Sorry abou that, and thanks guys!
I see that I am supposed to run adprep/forestprep and adprep/domainprep on the 2003 R2 server, but what adprep commands am I supposed to run on the 2000 server?
nevermind, it looks like adprep /forestprep and adprep /domainprep, as I dicussed with KTCS that it has to be run onthe 2000 server, not the 2003
surprisingly more common than you would think :)
