All our offices are connected via VPNs. We have several remote locations that do NOT have a DC in the same location. When joining a computer to the domain/changing settings/etc we are forced to change the DNS settings on the client computer to point to a DC at another location.
Is this always required? How can we make these changes without a DC being onsite? Users cannot even change their passwords unless we point their DNS to a DC.
Our entire Domain is WIndows 2008 servers.
