I am wondering if there are any issues with creating a trust between two domain, one where its DCs are sitting at W2K3 R2/SP2 and the other domain's DCs are sitting at only W2K3 SP2?
1) I need to know if there will be any incompatibility problems
2) Replication (in general) / Replication speed issues?
3) How does this difference in the OS levels affect AD communication, if at all?
Need some documentation that supports your answers. Thanks, much!
