If all machines are installed Windows 7, you can create a HomeGroup instead of Workgroup. HomeGroup is designed to make sharing resources likes files and printers much easier by abstracting many of the concepts like sharing permissions and user accounts and passwords so that all the complicated choices get made for the user in the background. The user only has to decide which content they would like the share, and whether they want the person they are sharing with to be able to make changes to their content. However, HomeGroup is only available for Windows 7 machine. If there is other system, such as Windows Vista or Windows XP, you have to create a Workgroup and assign sharing permissions to certain document. Cdobbs has already listed the detail steps to create Workgroup. Thanks, Novak
