SYMPTOMS
On a server that has four CPUs, if you upgrade from Microsoft Windows 2000 Server to Windows Server 2003, the Windows Server 2003 Setup program displays the following error message and then quits:

Exceeded Processor Count

=
===========

You have more CPUs installed in your machine than this version of Windows Server supports.

If you upgrade, one or more processors will be disabled.

For more information about processor restrictions in Windows Server, see the Microsoft Web site at http://www.microsoft.com/.

However, if you install Windows Server 2003 as the first Windows-based operating system on a server that has four CPUs, the Setup program does not warn you that Windows Server 2003 does not support all four CPUs. The installation completes successfully, but only two of the four CPUs are supported.



WORKAROUND
To work around this behavior, install Microsoft Windows 2000 Advanced Server.



STATUS
This behavior is by design.
