We do have two 2003 standard SP1 domain controllers and few member server. Two of my member servers do have 2003 R2 installed. Ideally I 'would like to switch licenses so that my DC will have R2 and members will be downgraded to standard 2003. Is it possible to do without getting into a lot of aggregation?
The reason is that I’d like to use R2 functionality on Domain controllers while I don’t have any use for R2 additional functionality on my member servers.
