I am trying to consolidate an old file server (named server3) onto a newer one (named server2).
I want to give server2 a second name (server3), allowing every workstations to use it without any change.
I tested with a modified host file on a workstation and it was okay (with the use of
OptionalNames registry setting on server2). So I created a CNAME for server3 but it failed because the workstations don't have any dns prefix configured.
As we have many workstations on several places, it is difficult to reconfigure every workstations.
How can I make server2 to register into AD with its second name?
How can I make the DNS to resolve server3 without suffix ?
note: when someone writes an answer, I don't understand how to answer to this.
