incompatibility of win2k3 r2, win2k3 sp1, and win2k

Before you can introduce Windows Server 2003 domain controllers, you must prepare the forest and domains with the ADPrep utility.

* ADPrep /forestprep on the schema master in your Windows 2000 forest.
* ADPrep /domainprep on the Infrastructure Master in each AD domain.

ADPrep is located in the i386 directory of the Windows Server 2003 install media.

Note: In Windows Server 2003 R2, ADPrep is not located in the same folder as in the older Windows Server 2003 media, and instead you need to look for it in the second CD. You see, Windows Server 2003 R2 comes on two installation disks. Installation disk 1 contains a slip-streamed version of Windows Server 2003 with Service Pack 2 (SP2). Installation disk 2 contains the Windows Server 2003 R2 files.

The correct version of the ADPrep.exe tool for Windows Server 2003 R2 is 5.2.3790.2075.

You can find the R2 ADPrep tool in the following folder on the second CD:

drive:\CMPNENTS\R2\ADPREP\



Note, running adprep on the PDC should be good enough.
