Windows Server 2003 R2 installation disks
Windows Server 2003 R2 comes on two installation disks. Installation disk 1 contains a slip-streamed version of Windows Server 2003 with Service Pack 1 (SP1). Installation disk 2 contains the Windows Server 2003 R2 files.

Installation disk 2 is specific to the edition of Windows Server 2003. For example, you must use a Windows Server 2003 R2, Standard Edition installation disk to upgrade a Windows Server 2003, Standard Edition-based computer. Installation disk 2 contains installation files for the x86-based version and the x64-based version of Windows Server 2003 R2.
The Adsiedit.exe utility and the Ldp.exe utility are included with Windows Server 2003 R2 support tools. To install support tools, run Suptools.msi from the \Support\Tools folder on installation disk 1.
