Deploy exchange 2003 with x64 domain controllers

I'm looking for a way to deploy an exchange 2003 server in my domain. The problem I'm having occurs while running forestprep on my domain controller:

"Microsoft Exchange Server has a known compatibility issue with this version of Windows. For more information, refer to....."

My domain controller has Windows server 2003 x64 standard edition SP2 installed. I have two backup domain controllers, unfortunately with the exact same configuration. Is there a way to get the schema updates done on a x64 domain controller?

I don't mind running exchange server 2003 on x86, I understand that's the only way. I have a seperate dedicated server ready and awaiting the exchange installation. However, not being able to deploy forestprep and domainprep halts me before I got started... Any help would be greatly appreciated!

You can't run prep from x64 domain controllers. You will need to use a x86 machine to do that. Prep does not have to be run from a domain controller, so you can use the server that you are going to install Exchange on.

The warning about having an issue with this version of Windows will always appear on Windows 2003 post SP1. In most cases it can be ignored, as the "issue" is rather obscure.

Worked like a charm. I just finished running the forestprep and domainprep from the soon-to-be exchange server, and it finished without errors. Thanks for the provided solution!

In my humble opinion (IMHO), TouchDown from Symantec is the best in class for this type of application, but Symantec has end-of-lifed it and although one can keep using it, it will no longer be supported or upgraded.  Time to look for alternatives t…
