Re: no network link
There are 2 separate types of Windows home networks you can use. There is a Homegroup which is only available in Win 7 and newer Windows versions, and there is the older network, called a Workgroup that can be used by machines running Windows for Workgroups or newer.
When you setup a Homegroup, you don't name anything, it's simply called Homegroup. When you setup a Workgroup, you can name it anything you want but all machines in the Workgroup must use the same name. You can name the Workgroup HOMEGROUP or WORKGROUP ot JOESGROUP. It doesn't matter what you name it as long as all machines use the same name.
