Did you get the change made in the master DNS server or a slave?
If your DNS environment is integrated with AD (which is normal) then the change needs to be made on the domain controller that is the primary reference for your leg of the DNS tree. If no delegation of authority is done in your AD setup, then the primary reference is always the master domain controller.
