ADPREP Windows 2000 Server to 2008R2. By dave 9 years ago. Upgrade 2000 Domain. Add 2008 R2 DC You have to run ADPREP(32) on the old server to bring Forest and AD etc up to the new specs.

When you are using Windows Server 2003 or Windows Server 2008 32bit Domain Controllers, it seems that you cannot simply extend schema manually using Windows Server 2012/2012R2 adprep utility. Especially if you do not need to promote new Windows Server 2012/2012R2 Domain Controller. Previous Windows Server versions like: • Windows Server 2003 • Windows Server 2008 contained only 32bit adprep utility. In Windows Server 2008R2 there were two adprep tool versions: • adprep32.exe for 32bit operating systems • adprep.exe for 64bit operating systems When Windows Server 2012 was released only one 64bit adprep version is available. There is no more 32bit tool to extend schema. With this Windows version new feature called transparent adpreping was introduced. This feature allows Active Directory promotion wizard automatically extend schema and prepare Infrastructure Master if it was ran with appropriate credentials: • Enterprise Admin or Schema Admin to extend schema • Enterprise or Domain Administrator to prepare Infrastructure Master But what if you have 32bit Domain Controllers in your environment and you wish to extend schema without implementing Windows Server 2012/2012R2 DC?

To check them, mount DVD media or ISO file to any 64bit OS machine in your domain environment.

Anyway, a nice experience to enjoy this classic record on vinyl. The vocals sounds good but the music and beats sounds kind of low.
