Remove DNS from demoted domain controller
so I've spent the last few days migrating my DC's to new 2k8 R2 servers and demoting my old ones. Everyting looks alright, all the roles are migrated across to the new servers and they are now running AD and DNS. My problem is that the old servers still seem to be running (my AD integrated) DNS.
Does anyone have any advice about stopping them doing that? i.e can I just stop the DNS service on them? IS there anything else I need to do or look out for?
