Preparing for ADPrep
Before you can install your first R2 domain controller, you have to go through the process of upgrading your existing schema to Windows Server 2003 R2 with the ADPrep utility. If you've upgraded from Windows 2000 to Windows Server 2003 AD, you are undoubtedly familiar with the adprep.exe
/forestprep switch; if not, please review Chapter 14. This switch is run independently from the domain controller promotion to allow Active Directory administrators to take care of the AD-related tasks necessary to support Windows Server 2003 R2 Active Directory. The R2 ForestPrep
process extends the schema to include the objects and attributes necessary for the R2 Feature Packs, primarily the Unix interoperability functions.
Unlike the Windows 2000 to Windows Server 2003 upgrade, you do not have to run adprep.exe
/domainprep for the Windows Server 2003 to Windows Server 2003 R2 Upgrade, as there are no domain-level changes that need to be implemented.
If upgrading from Windows 2000 to Windows Server 2003 R2, however, you do need to run adprep.exe
/domainprep. See Chapter 14 for details; the process is the same as it is under the gold version of Windows Server 2003.
Warning
Windows Server 2003 Service Pack 1 is required to load R2.
The ADPrep command can be found in the \CMPNENTS\R2\ADPREP directory on Windows Server 2003 R2 disc 2. The ADPrep command depends on several files that reside in that directory, so it cannot simply be copied out and put on a floppy or CD by itself. ...
