Adding another domain controller

I am currently running a windows 2003 domain with 2 domain controllers that are running Windows 2003 SP2 Enterprise edition and I want to add a new machine that is running Windows 2003 R2 SP2 Enterprise Edition. The problem I am having is that when I run the Active Directory Installation Wizard on the new server I get an error that it could not complete because the forest is not prepared for installing Windows Server 2003, even though my Forest and Domain say that they are at 2003 the highest level. The error also says that the version of active directory schema of the source forest is not compatible with the version of active directory on this computer.

Have you run adprep /forestprep and adprep /domainprep?

adprep should be on CD2 of server.
Hi,

Are there any other errors in the event viewers on either of the servers? Is there any other servers in your network? Also, can you paste the exact error message text here.

Cheers,
Perry

I have run adprep with the the R2 cd and get the following message I think I may have left out that the new server I am trying to add as a domain controller is 64bit and my current servers are 32bit.

Microsoft Windows [Version 5.2.3790]

C:\Documents and Settings\Administrator.PDCSTL>d:

D:\>cd \CMPNENTS\R2\ADPREP

D:\CMPNENTS\R2\ADPREP>adprep /forestprep
The image file D:\CMPNENTS\R2\ADPREP\ADPREP.EXE is valid, but is for a machine t
ype other than the current machine.

D:\CMPNENTS\R2\ADPREP>

You should be able to run this on your new 64-bit server (so long as it's a member of the domain).

I have tried that and this is what I get.

D:\>cd \cmpnents\r2\adprep

D:\CMPNENTS\R2\ADPREP>adprep /forestprep
Adprep cannot run on this platform because it is not a domain controller.
[Status/Consequence]
Adprep stopped without making any changes.
[User Action]
Run Adprep on a domain controller.

Sorry, my memory's a little fuzzy! :)

You can get a 32-bit version of 2003 R2 AdPrep utility from Microsoft (I'm kinda surprised they don't put it on the CD...)

Looks like you can click the "View and request hotfix downloads" link in the top-left corner of the window.

Sorry...was waiting for MS to e-mail me the hotfix so I could take a look at it for you, didn't realize my spam filter got it.

Looks like you can extract it anywhere you like, then go to a command prompt and change directory to x86 and run adprep.exe.
