We have a domain which has several child domains hanging off it. We are upgrading the domain from 2000 to 2003. So far we have upgraded some of the servers in the root domain – the forest FSMO role holder and our two primary DNS servers are amongst them. The domain level FSMO role holder is still on win2k.
We have been rolling out windows 2003 it a bit of a random fashion to the child domain controllers (we have given them no real order. I am finding that the controllers that are being upgraded are having issues as they can not replicate their DNS partition because their replication partners don’t have this information as they are still running windows 2000. Should I be concerned with these errors? Or should I change the order in which I upgrade the servers?
