Adding an additional domain controllers to your domain does not effect user authentication. not sure what you mean by data profile? If the first DC has issues, users will authenticate to the second DC until the first DC is available again. At that moment, sessions will be on either of the two DC's
Thanks for your support. your response is logical.
