When you ordered your hosting package you would have chosen Windows hosting or Linux Hosting. For Windows shared hosting we use the Plesk or Parellels control panel. When you login the title bar at the top says Parellels this is a windows IIS hosting account.
A Linux server we use the control Panel C-Panel to let you manage your account .
We provide flash tutorials for both control panels. If you are still not sure check with support by opening a ticket.
