Configure BranchCache for network files

This policy setting is used only when you have deployed one or more BranchCache-enabled file servers at your main office. This policy setting specifies when client computers in branch offices start caching content from file servers based on the network latency – or delay – that occurs when the clients download content from the main office over a Wide Area Network (WAN) link. When you configure a value for this setting which is the maximum round trip network latency allowed before caching begins clients do not cache content until the network latency reaches the specified value; when network latency is greater than the value clients begin caching content after they receive it from the file servers. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache latency 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 latency 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 latency settings on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the latency setting that you use on individual client computers. – Enabled. With this selection the BranchCache maximum round trip latency setting is enabled for all client computers where the policy is applied. For example if Configure BranchCache for network files is enabled in domain Group Policy the BranchCache latency setting that you specify in the policy is turned on for all domain member client computers to which the policy is applied. – Disabled. With this selection BranchCache client computers use the default latency setting of 80 milliseconds. In circumstances where this policy setting is enabled you can also select and configure the following option:- Type the maximum round trip network latency (milliseconds) after which caching begins. Specifies the amount of time in milliseconds after which BranchCache client computers begin to cache content locally.

Set BranchCache Distributed Cache mode

This policy setting specifies whether BranchCache distributed cache mode is enabled on client computers to which this policy is applied. In addition to this policy you must use the policy “Turn on BranchCache” to enable BranchCache on client computers. In distributed cache mode client computers download content from BranchCache-enabled main office content servers cache the content locally and serve the content to other BranchCache distributed cache mode clients in the branch office. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache 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 enable BranchCache on all client computers you can specify Not Configured for this domain Group Policy setting and then configure local computer policy to enable BranchCache on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the enabled setting that you use on individual client computers where you want to enable BranchCache. – Enabled. With this selection BranchCache distributed cache mode is enabled for all client computers where the policy is applied. For example if this policy is enabled in domain Group Policy BranchCache distributed cache mode is turned on for all domain member client computers to which the policy is applied. – Disabled. With this selection BranchCache distributed cache mode is turned off for all client computers where the policy is applied. * This policy setting is supported on computers that are running Windows Vista Business Enterprise and Ultimate editions with Background Intelligent Transfer Service (BITS) 4. 0 installed.

Set BranchCache Hosted Cache mode

This policy setting specifies whether BranchCache hosted cache mode is enabled on client computers to which this policy is applied. In addition to this policy you must use the policy “Turn on BranchCache” to enable BranchCache on client computers. When a client computer is configured as a hosted cache mode client it is able to download cached content from a hosted cache server that is located at the branch office. In addition when the hosted cache client obtains content from a content server the client can upload the content to the hosted cache server for access by other hosted cache clients at the branch office. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache 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 enable BranchCache on all client computers you can specify Not Configured for this domain Group Policy setting and then configure local computer policy to enable BranchCache on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the enabled setting that you use on individual client computers where you want to enable BranchCache. – Enabled. With this selection BranchCache hosted cache mode is enabled for all client computers where the policy is applied. For example if this policy is enabled in domain Group Policy BranchCache hosted cache mode is turned on for all domain member client computers to which the policy is applied. – Disabled. With this selection BranchCache hosted cache mode is turned off for all client computers where the policy is applied. In circumstances where this setting is enabled you can also select and configure the following option:- Type the name of the hosted cache server. Specifies the computer name of the hosted cache server. Because the hosted cache server name is also specified in the certificate enrolled to the hosted cache server the name that you enter here must match the name of the hosted cache server that is specified in the server certificate. Hosted cache clients must trust the server certificate that is issued to the hosted cache server. Ensure that the issuing CA certificate is installed in the Trusted Root Certification Authorities certificate store on all hosted cache client computers. * This policy setting is supported on computers that are running Windows Vista Business Enterprise and Ultimate editions with Background Intelligent Transfer Service (BITS) 4. 0 installed.

Set percentage of disk space used for client computer cache

This policy setting specifies the default percentage of total disk space that is allocated for the BranchCache disk cache on client computers. If you enable this policy setting you can configure the percentage of total disk space to allocate for the cache. If you disable or do not configure this policy setting the cache is set to 5 percent of the total disk space on the client computer. Policy configurationSelect one of the following:- Not Configured. With this selection BranchCache client computer cache 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 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 settings on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the client computer cache setting that you use on individual client computers. – Enabled. With this selection the BranchCache client computer cache setting is enabled for all client computers where the policy is applied. For example if Set percentage of disk space used for client computer cache is enabled in domain Group Policy the BranchCache client computer cache setting that you specify in the policy is turned on for all domain member client computers to which the policy is applied. – Disabled. With this selection BranchCache client computers use the default client computer cache setting of five percent of the total disk space on the client computer. In circumstances where this setting is enabled you can also select and configure the following option:- Specify the percentage of total disk space allocated for the cache. Specifies an integer that is the percentage of total client computer disk space to use for the BranchCache client computer cache. * This policy setting is supported on computers that are running Windows Vista Business Enterprise and Ultimate editions with Background Intelligent Transfer Service (BITS) 4. 0 installed.

Turn on BranchCache

This policy setting specifies whether BranchCache is enabled on client computers to which this policy is applied. In addition to this policy setting you must specify whether the client computers are hosted cache mode or distributed cache mode clients. To do so configure one of the following the policy settings: – Set BranchCache Distributed Cache mode- Set BranchCache Hosted Cache mode- Configure Hosted Cache ServersPolicy configurationSelect one of the following:- Not Configured. With this selection BranchCache 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 enable BranchCache on all client computers you can specify Not Configured for this domain Group Policy setting and then configure local computer policy to enable BranchCache on individual client computers. Because the domain Group Policy setting is not configured it will not over-write the enabled setting that you use on individual client computers where you want to enable BranchCache. – Enabled. With this selection BranchCache is turned on for all client computers where the policy is applied. For example if this policy is enabled in domain Group Policy BranchCache is turned on for all domain member client computers to which the policy is applied. – Disabled.
