We have a placeholder domain at the root of our forest. There are two dc's one in AU and one in US. The AU one being the schema master.
We want to install exchange 2007 sp1 into our child domain which spans many countries. Currently the RID and PDC roles are a win2k sp4 box. The infrastructure master is a wind2k3 sp2 server and the domain function level is windows 2000 native. Currently AU hosts the only 2k7 server in the org. It works fine however we do get 'The domain controller dc#.domain.com is running Windows 5.0 (2195) (Unknown Service Pack). Exchange Active Directory Provider requires that domain controllers are running Windows Server 2003 Service Pack 1 or later versions of Windows' warnings. I have used vmware to test installation of sp1 on our 2 exchange 2007 servers with the 2 AU child dcs and the au root dc after some jigging with the schema extensions in the root domain with the 32bit sp21. This process worked however it is an isolated test as it doesn't talk to the rest of our dc's on the wan being a test network. I guess the thing im trying to figure now is whether we will have more issues after sp1 is applied with windows 2000 dc's still hanging around and if it is better to upgrade them to win2k3 sp2 first. There are 8 win2k dcs out of 15. Anyone had any experience in a similar environment to this or could offer any input, i'd be listening.
