Normally when installing SQL Server 2014 express on a domain computer the service is normally NT Service. What is the best way to install SQL Server 2014 express on a computer with a workgroup. I'm running into issues where the logged in user or service does not have permissions to the server/database. Can anyone help or tell me what I need to do to install it without running into these permission issues? Also what Local Security Policies for the user may need to be granted.
