Windows Server 2008 / Windows server 2003 forest Prep Errors

I get the following message even though ADPREP / FORESTPREP has been run successfully---
" To install a domain controller into this active directory forest you  must first prepare the forest using adprep/ forestprep. The adprep utility is available on windows server 2008 R2 installation media in the \support\adprep folder"
--------------------------------------------------------------------------------------------------------------------
Server 2008 DNS is pointed to the windows server 2003 DNS / domain controller
---------------------------------------------------------------------------------------------------------------------
When i try and run forest prep again i get the message that its already complete

Which adprep version did you run?

adprep32 or adprep? Windows Server 2008 R2 is 64 bit OS and your Windows 2003 is probably 32 bit, so you should use

adprep32 /forestprep
on Schema Master

and

adprep32 /domainprep /gpprep
on Infrastructure Master

are you logged in as a schema admin?
have you installed all the MS recommended hotfixes and patches?
What functional level is your domain?
are you running this on the server which is the schema master?
Krzysztof PytkoSenior Active Directory EngineerCommented:
If you don't know which server holds those roles in your environment, log on to one DC and from command-line type

netdom query fsmo

then locate Schema and Infrastructure Masters

and one more thing. What is your domain functional level (Windows 2000 Mixed, Windows 2000 Native, Windows 2003)?

Windows 2000 native

Lets step back a bit and take a quick look at the basics.
You are implementing a new 2008R2 AD DS into your existing 2003 AD.

What is the 2003 environment background. Was it a 2003 only deployment ? Or was it also upgraded from a previous version.

DCDIAG or NLTest are your friends on all things FSMO. Run a test all on either of them to confirm if your Schema and Infrastructure master are ok and responding as expected.

Please paste the dcdiag summary

Ahh 2000 native.
Do u  have any 2000 domain controllers in the forest?
If you run Replmon on the 2003 domain controller and you open up a connection to the local host. Does replmon pass without incident when querying the Fsmo

petri actually has a clearer article
and it mentions the need to use the 32bit version as mentioned earlier

Thanks for help this particular problem is resolved. Running ADPrep32 did it
DarinTCHSenior CyberSecurity EngineerCommented:
glad we could help
I often forget the Win 2008 DVD has 64 bit tools as primary
need to look elsewhere if running on older or x64 system
