A Task Scheduler problem

I have a script that takes backups of a client's SQL Server databases at a specific time every evening using Task Scheduler.
We then installed SQL Server 2014 at the client so this necessitated me having to re-install my backup script and recreate the Task Scheduler job.
Now it gives this error: " Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : Login failed for user 'AFRICASUNOIL\abdulhamid'.."
Can someone help ?

does the script run on the same machine as the server?
is the TCP/IP protocol enabled in the SQL Server configuration?
Could it be a firewall issue? Desactivate it for 10 minutes the time to run your test
Is the server name and/or instance name have changed?
was your user recreated on the new server?

Have you had a chance to test the ODBC driver connection with that account to rule out whether this is a driver/compatability issue or a specific user account issue?

Hi Eric,
The last one of your question suggestions was the cause of the problem.
The user concerned had not been recreated on the new server.
