Larvel MSSQL connection only working in CLI

I have a Laravel 5 installation, when I run artisan migrate everything works fine but when I try to access any pages on the front end which access the SQL database I get a login failed error, which is my domain and computer name and not the user which I expect to see. Using Windows authentication. Server information is correct in .env hence artisan is working but I need help as to why the same details aren't working on the front end.

Thanks.
