This policy setting controls whether folders are redirected on a user's primary computers only. This policy setting is useful to improve logon performance and to increase security for user data on computers where the user might not want to download private data such as on a meeting room computer or on a computer in a remote office.To designate a user's primary computers an administrator must use management software or a script to add primary computer attributes to the user's account in Active Directory Domain Services (AD DS). This policy setting also requires the Windows Server 2012 version of the Active Directory schema to function.If you enable this policy setting and the user has redirected folders such as the Documents and Pictures folders the folders are redirected on the user's primary computer only.If you disable or do not configure this policy setting and the user has redirected folders the folders are redirected on every computer that the user logs on to.Note: If you enable this policy setting in Computer Configuration and User Configuration the Computer Configuration policy setting takes precedence.
