We have a 2000 server running Exchange 2000, DNS, and serving as our only DC (yes, I know it's not smart). The only suitable servers we have to be secondary DC's are running server 2003. Is it even possible to have a 2003 server as a secondary DC to a 2000 DC, and if so, are there any hurdles I should expect to overcome? I've been reading up on how to create secondary DC's, but want to know what I'm getting myself into. i've also considered bringing up another 2003 server as a DC and migrating the exchange installation over to the new server as well, but have seen articles that indicate demoting a DC running exchange will create a rip in the space-time continuum, thus destroying the universe. Thanks in advance...

2000 AD Domains with 2003 Secondary DC's

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
