I have a Windows 2000 Server environment and I recently purchased a Windows 2003 server. Can I still leave the network environment as is with a 2000 server as the domain controller and add a 2003 server as a member server? Later, I will upgrade the entire network to WIndows 2003, but not for another month or two. If this will create problems, then I will wait. I look forward to your answer. Thanks.
