I am upgrading from Windows NT to Windows 2003. The only things that are NT are the PDC and BDCs; everything else is 2000 or 2003 member servers. My question is, when I upgrade my Windows NT domain controllers to 2003, will I need to do anything else to my Windows 2000/2003 member servers that were in the NT domain?
Your existing member servers, regardless of operating system, will simply become member servers in your upgraded AD domain. If you will be using Organizational Units and Group Policy (and I hope you are), you'll probably want to move them to a specific OU for administration and policy application, since they'll be in the default "Computers" container immediately following the upgrade.
