Check your DC(Domain Controller) first. It is responsible for authenticating username & password. Also make sure you are using right Port ( SQL server). Also told your network admin to set up a "Trust" relation between the domains Or create a login username/password on remote SQL Server & configure it to allow SQL Server authentication .
