When you first install Windows, it asks if you are going to use the operating system for personal use or connect to a work/school account. Are you using this machine in an actual business location or are you connecting remotely? If you're connecting remotely, the company has to provide you a method to connect to their network. The business account is provided by the business that you utilize. If you are directly within the business, you have to connect to their provided network. All information required to use that business account would be provided by the business (username, account information, domain name, etc.). You have to make sure that you can connect to a network with Windows and that can be done via the Parallels Configure section while in the VM .
