Incompatability Error running setup /forestprep during Exchange 2003 installation on Windows Server 2003 R2

 When I begin the installation procedure for Exchange 2003  with the setup  /ForestPrep command on a new Windows Server R2 server I get a message regarding an compatibility with this version and a reference link to a Microsoft website link that does not appear to be related to the error.  If I select Continue on the message box, I get the message again.  I Continue once again, and the process just hangs.

This is a retail boxed version of Exchange 2003.  It has never been installed, so cannot be upgraded to Exchange 2003 SP1 or SP2 (I believe).

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The error message is fine.
It is the service pack that is causing the error message to popup. Unless you using a cluster it can be bypassed.

You can't slipstream Exchange, so everyone has to go through the error message.
You can run the forestprep and domainprep from any machine in the domain - I usually run it on a DC as that is where the information will end up.
