Disable: 'Prevent the computer from joining a homegroup' By default, users can add their computer to a homegroup on a home network. If you enable this policy setting, a user on this computer will not be able to add this computer to a homegroup. This setting does not affect other network sharing features. If you disable or do not configure this policy setting, a user can add this computer to a homegroup. However, data on a domain-joined computer is not shared with the homegroup. Counter Measure: Enable this setting to prevent computers from joining a HomeGroup. Potential Impact: Mobile users who access printers and other shared devices on their home networks will not be able to leverage the ease of use provided by HomeGroup functionality.
