I have a new network that needs to be upgraded to Server 2008. One requirement is the eventual upgrade of Exchange 2003 to Exchange 2010. The only issue is the use of a couple servers that are running Windows Server 2000 SP3. From my understanding, SP4 must be installed to raise the Forest Functional Level to 2003 Native. The next obvious question is, can Server 2000 coexist without issue in an environment with Domain Controllers running Server 2008 x64 OS'es? Has anyone had experience with this configuration?
Your help is greatly appreciated!
