This policy setting specifies the default age in days for which segments are valid in the BranchCache data cache on client computers. If you enable this policy setting you can configure the age for segments in the data cache. If you disable or do not configure this policy setting the age is set to 28 days. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache client computer cache age settings are not applied to client computers by this policy. In the circumstance where client computers are domain members but you do not want to configure a BranchCache client computer cache age setting on all client computers you can specify Not Configured for this domain Group Policy setting and then configure local computer policy to enable BranchCache client computer cache age settings on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the client computer cache age setting that you use on individual client computers. – Enabled. With this selection the BranchCache client computer cache age setting is enabled for all client computers where the policy is applied. For example if this policy setting is enabled in domain Group Policy the BranchCache client computer cache age that you specify in the policy is turned on for all domain member client computers to which the policy is applied. – Disabled.

In circumstances where this setting is enabled you can also select and configure the following option:- Specify the age in days for which segments in the data cache are valid.

This policy setting specifies whether client computers are configured to use hosted cache mode and provides the computer name of the hosted cache servers that are available to the client computers. Hosted cache mode enables client computers in branch offices to retrieve content from one or more hosted cache servers that are installed in the same office location. You can use this setting to automatically configure client computers that are configured for hosted cache mode with the computer names of the hosted cache servers in the branch office. If you enable this policy setting and specify valid computer names of hosted cache servers hosted cache mode is enabled for all client computers to which the policy setting is applied. For this policy setting to take effect you must also enable the “Turn on BranchCache” policy setting. This policy setting can only be applied to client computers that are running at least Windows 8. This policy has no effect on computers that are running Windows 7 or Windows Vista. Client computers to which this policy setting is applied in addition to the “Set BranchCache Hosted Cache mode” policy setting use the hosted cache servers that are specified in this policy setting and do not use the hosted cache server that is configured in the policy setting “Set BranchCache Hosted Cache Mode. “If you do not configure this policy setting or if you disable this policy setting client computers that are configured with hosted cache mode still function correctly. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache settings are not applied to client computers by this policy setting. – Enabled. With this selection the policy setting is applied to client computers which are configured as hosted cache mode clients that use the hosted cache servers that you specify in “Hosted cache servers. “- Disabled. With this selection this policy is not applied to client computers. In circumstances where this setting is enabled you can also select and configure the following option:- Hosted cache servers. To add hosted cache server computer names to this policy setting click Enabled and then click Show. The Show Contents dialog box opens. Click Value and then type the computer names of the hosted cache servers.

This policy setting specifies whether BranchCache-capable client computers operate in a downgraded mode in order to maintain compatibility with previous versions of BranchCache. If client computers do not use the same BranchCache version cache efficiency might be reduced because client computers that are using different versions of BranchCache might store cache data in incompatible formats. If you enable this policy setting all clients use the version of BranchCache that you specify in “Select from the following versions. “If you do not configure this setting all clients will use the version of BranchCache that matches their operating system. Policy configurationSelect one of the following:- Not Configured. With this selection this policy setting is not applied to client computers and the clients run the version of BranchCache that is included with their operating system. – Enabled. With this selection this policy setting is applied to client computers based on the value of the option setting “Select from the following versions” that you specify. – Disabled. With this selection this policy setting is not applied to client computers and the clients run the version of BranchCache that is included with their operating system. In circumstances where this setting is enabled you can also select and configure the following option:Select from the following versions- Windows Vista with BITS 4. 0 installed Windows 7 or Windows Server 2008 R2. If you select this version later versions of Windows run the version of BranchCache that is included in these operating systems rather than later versions of BranchCache. – Windows 8. If you select this version Windows 8 will run the version of BranchCache that is included in the operating system.

This policy setting specifies whether client computers should attempt the automatic configuration of hosted cache mode by searching for hosted cache servers publishing service connection points that are associated with the client’s current Active Directory site. If you enable this policy setting client computers to which the policy setting is applied search for hosted cache servers using Active Directory and will prefer both these servers and hosted cache mode rather than manual BranchCache configuration or BranchCache configuration by other group policies. If you enable this policy setting in addition to the “Turn on BranchCache” policy setting BranchCache clients attempt to discover hosted cache servers in the local branch office. If client computers detect hosted cache servers hosted cache mode is turned on. If they do not detect hosted cache servers hosted cache mode is not turned on and the client uses any other configuration that is specified manually or by Group Policy. When this policy setting is applied the client computer performs or does not perform automatic hosted cache server discovery under the following circumstances:If no other BranchCache mode-based policy settings are applied the client computer performs automatic hosted cache server discovery. If one or more hosted cache servers is found the client computer self-configures for hosted cache mode. If the policy setting “Set BranchCache Distributed Cache Mode” is applied in addition to this policy the client computer performs automatic hosted cache server discovery. If one or more hosted cache servers are found the client computer self-configures for hosted cache mode only. If the policy setting “Set BranchCache Hosted Cache Mode” is applied the client computer does not perform automatic hosted cache discovery. This is also true in cases where the policy setting “Configure Hosted Cache Servers” is applied. This policy setting can only be applied to client computers that are running at least Windows 8. This policy has no effect on computers that are running Windows 7 or Windows Vista. If you disable or do not configure this setting a client will not attempt to discover hosted cache servers by service connection point. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache settings are not applied to client computers by this policy setting and client computers do not perform hosted cache server discovery. – Enabled. With this selection the policy setting is applied to client computers which perform automatic hosted cache server discovery and which are configured as hosted cache mode clients. – Disabled. With this selection this policy is not applied to client computers.

This policy setting configures the Program Compatibility Assistant (PCA) to diagnose failures with application and driver compatibility. If you enable this policy setting the PCA is configured to detect failures during application installation failures during application runtime and drivers blocked due to compatibility issues. When failures are detected the PCA will provide options to run the application in a compatibility mode or get help online through a Microsoft website. If you disable this policy setting the PCA does not detect compatibility issues for applications and drivers. If you do not configure this policy setting the PCA is configured to detect failures during application installation failures during application runtime and drivers blocked due to compatibility issues. Note: This policy setting has no effect if the “Turn off Program Compatibility Assistant” policy setting is enabled. The Diagnostic Policy Service (DPS) and Program Compatibility Assistant Service must be running for the PCA to run. These services can be configured by using the Services snap-in to the Microsoft Management Console.

This policy setting determines whether offline files are synchronized in the background when it could result in extra charges on cell phone or broadband plans. If you enable this setting synchronization can occur in the background when the user’s network is roaming near or over the plan’s data limit. This may result in extra charges on cell phone or broadband plans. If this setting is disabled or not configured synchronization will not run in the background on network folders when the user’s network is roaming near or over the plan’s data limit. The network folder must also be in “slow-link” mode as specified by the “Configure slow-link mode” policy to avoid network usage.
