Item (3) is not correct.

 

Certain features of Exchange 2003 require Windows 2003 AD; but Exchange 2003
will, in general, work on Windows 2000 AD quite happily.

 

But I absolutely agree with your other conclusions and recommendations.

You have 3 problems that are combing to create a super problem:

 

1. Exchange 2000 & 2003 are integrated/rely on Active directory. When
Exchange is installed on a DC, it is a permanent bond that can not be
broken. As far as Exchange is concerned, there is no other DC in the world.

 

2. Exchange 2000 will not run on Windows Server 2003. Therefore, to upgrade
to Exchange 2003, you must first upgrade Exchange 2000 to Exchange 2003, and
then upgrade the OS.

 

3. Exchange 2003 requires Windows 2003 Active Directory.

 

Super Problem: Since to upgrade to Exchange 2003 you have to first access
Windows 2003 Active directory, and since Exchange is installed on a DC and
it is a permanent bond, you must first upgrade the OS to Windows 2003 BUT
you can not do that because Exchange 2000 will not run on Windows 2003 and
therefore you will not be able to upgrade it to Exchange 2003.

 

So, IMHO, the recommended course of action is to create a new server running
Windows 2000 and Exchange 2000 and NOT a DC. Migrate mailboxes to that
server. Demote the current Exchange server, uninstall Exchange and drop the
server from the domain. Now, upgrade your Active directory to Windows 2003.
Upgrade Exchange 2000 to 2003 and then upgrade the underlying OS to Windows
2003.

 

Yes, a lot of work and time. But then again, that is why MS publishes white
papers ahead of time telling people not to install Exchange onto a DC.
