create other user for backup exec

Hi, I have an appliance 3600 with backup exec 2014 so I want to create a other user for backup exec.

For example, the user administrator is the default account and I want other user like backup.symantec

When a I use administrator all is fine and works right but when I want use backup.symantec I have not connection with the BkupLnch

The user.backup has role in windows Backup Operators, Remote Desktop Users and Users.

My question is, this is right or i have to do other configuration?
