Event logging level

Determines which events the Offline Files feature records in the event log. Offline Files records events in the Application log in Event Viewer when it detects errors. By default Offline Files records an event only when the offline files storage cache is corrupted. However you can use this setting to specify additional events you want Offline Files to record. To use this setting in the “Enter” box select the number corresponding to the events you want the system to log. The levels are cumulative; that is each level includes the events in all preceding levels. “0” records an error when the offline storage cache is corrupted. “1” also records an event when the server hosting the offline file is disconnected from the network. “2” also records events when the local computer is connected and disconnected from the network. “3” also records an event when the server hosting the offline file is reconnected to the network. Note: This setting appears in the Computer Configuration and User Configuration folders. If both settings are configured the setting in Computer Configuration takes precedence over the setting in User Configuration.

Encrypt the Offline Files cache

This policy setting determines whether offline files are encrypted. Offline files are locally cached copies of files from a network share. Encrypting this cache reduces the likelihood that a user could access files from the Offline Files cache without proper permissions. If you enable this policy setting all files in the Offline Files cache are encrypted. This includes existing files as well as files added later. The cached copy on the local computer is affected but the associated network copy is not. The user cannot unencrypt Offline Files through the user interface. If you disable this policy setting all files in the Offline Files cache are unencrypted. This includes existing files as well as files added later even if the files were stored using NTFS encryption or BitLocker Drive Encryption while on the server. The cached copy on the local computer is affected but the associated network copy is not. The user cannot encrypt Offline Files through the user interface. If you do not configure this policy setting encryption of the Offline Files cache is controlled by the user through the user interface. The current cache state is retained and if the cache is only partially encrypted the operation completes so that it is fully encrypted. The cache does not return to the unencrypted state. The user must be an administrator on the local computer to encrypt or decrypt the Offline Files cache. Note: By default this cache is protected on NTFS partitions by ACLs. This setting is applied at user logon. If this setting is changed after user logon then user logoff and logon is required for this setting to take effect.

Allow or Disallow use of the Offline Files feature

This policy setting determines whether the Offline Files feature is enabled. Offline Files saves a copy of network files on the user’s computer for use when the computer is not connected to the network. If you enable this policy setting Offline Files is enabled and users cannot disable it. If you disable this policy setting Offline Files is disabled and users cannot enable it. If you do not configure this policy setting Offline Files is enabled on Windows client computers and disabled on computers running Windows Server unless changed by the user. Note: Changes to this policy setting do not take effect until the affected computer is restarted.

Subfolders always available offline

Makes subfolders available offline whenever their parent folder is made available offline. This setting automatically extends the “make available offline” setting to all new and existing subfolders of a folder. Users do not have the option of excluding subfolders. If you enable this setting when you make a folder available offline all folders within that folder are also made available offline. Also new folders that you create within a folder that is available offline are made available offline when the parent folder is synchronized. If you disable this setting or do not configure it the system asks users whether they want subfolders to be made available offline when they make a parent folder available offline.

Network Projector Port Setting

This policy setting allows you to select the TCP port that the Network Projector uses to send packets. If you enable this policy setting you can enter a TCP port number for the Network Projector. If you select a TCP port that is already in use by a system the Network Projector fails to initialize. If you enter zero (0) the operating system selects an available port. If you disable or do not configure this policy setting the operating system selects an available port. Note: Network port usage is dependent on how the “Turn off Connect to a Network Projector” policy setting is configured.

Turn off Connect to a Network Projector

This policy setting disables the Connect to a Network Projector wizard so that users cannot connect to a network projector. If you enable this policy setting users cannot use the Connect to a Network Projector Wizard to connect to a projector. If you disable or do not configure this policy setting users can run the Connect to a Network Projector Wizard to connect to a projector.

Subnet definitions are authoritative

This setting does not apply to desktop apps. Turns off Windows Network Isolation’s automatic discovery of private network hosts in the domain corporate environment. If you enable this policy setting it turns off Windows Network Isolation’s automatic discovery of private network hosts in the domain corporate environment. Only network hosts within the address ranges configured via Group Policy will be classified as private. If you disable or do not configure this policy setting Windows Network Isolation attempts to automatically discover your private network hosts in the domain corporate environment.

Default cache size

Limits the percentage of the computer’s disk space that can be used to store automatically cached offline files. This setting also disables the “Amount of disk space to use for temporary offline files” option on the Offline Files tab. This prevents users from trying to change the option while a setting controls it. Automatic caching can be set on any network share. When a user opens a file on the share the system automatically stores a copy of the file on the user’s computer. This setting does not limit the disk space available for files that user’s make available offline manually. If you enable this setting you can specify an automatic-cache disk space limit. If you disable this setting the system limits the space that automatically cached files occupy to 10 percent of the space on the system drive. If you do not configure this setting disk space for automatically cached files is limited to 10 percent of the system drive by default but users can change it. Tip: To change the amount of disk space used for automatic caching without specifying a setting in Windows Explorer on the Tools menu click Folder Options click the Offline Files tab and then use the slider bar associated with the “Amount of disk space to use for temporary offline files” option.

Non-default server disconnect actions

Determines how computers respond when they are disconnected from particular offline file servers. This setting overrides the default response a user-specified response and the response specified in the “Action on server disconnect” setting. To use this setting click Show. In the Show Contents dialog box in the Value Name column box type the server’s computer name. Then in the Value column box type “0” if users can work offline when they are disconnected from this server or type “1” if they cannot. This setting appears in the Computer Configuration and User Configuration folders. If both settings are configured for a particular server the setting in Computer Configuration takes precedence over the setting in User Configuration. Both Computer and User configuration take precedence over a user’s setting. This setting does not prevent users from setting custom actions through the Offline Files tab. However users are unable to change any custom actions established via this setting. Tip: To configure this setting without establishing a setting in Windows Explorer on the Tools menu click Folder Options click the Offline Files tab and then click Advanced. This setting corresponds to the settings in the “Exception list” section.

Specify administratively assigned Offline Files

This policy setting lists network files and folders that are always available for offline use. This ensures that the specified files and folders are available offline to users of the computer. If you enable this policy setting the files you enter are always available offline to users of the computer. To specify a file or folder click Show. In the Show Contents dialog box in the Value Name column type the fully qualified UNC path to the file or folder. Leave the Value column field blank. If you disable this policy setting the list of files or folders made always available offline (including those inherited from lower precedence GPOs) is deleted and no files or folders are made available for offline use by Group Policy (though users can still specify their own files and folders for offline use). If you do not configure this policy setting no files or folders are made available for offline use by Group Policy. Note: This setting appears in the Computer Configuration and User Configuration folders. If both policy settings are configured the policy settings will be combined and all specified files will be available for offline use.
