Enable Hash Publication for Non-Domain Member File Servers
Applies to: Windows Server (Semi-Annual Channel), Windows Server 2016
You can use this procedure to configure hash publication for BranchCache using local computer Group Policy on a file server that is running Windows Server 2016 with the BranchCache for Network Files role service of the File Services server role installed.
This procedure is intended for use on a non-domain member file server. If you perform this procedure on a domain member file server and you also configure BranchCache using domain Group Policy, domain Group Policy settings override local Group Policy settings.
Membership in Administrators, or equivalent is the minimum required to perform this procedure.
If you have one or more domain member file servers, you can add them to an organizational unit (OU) in Active Directory Domain Services and then use Group Policy to configure hash publication for all of the file servers at one time, rather than individually configuring each file server. For more information, see Enable Hash Publication for Domain Member File Servers.
