I would like to connect to the company's SQL Server 2014, where I am working at, with my computer using windows authentication. I need this to deploy from my machine SSIS packages, without having to access remotely our server's machine. 

I have been trying to add a login with my computer name plus my user as MY\_COMPUTER\USER, but I keep getting an error, which tells me the it wasn't able to find the domain of my computer. 

So, how can I connect my computer to our SQL Server using a windows authentication?
