Local Group Policy support for Windows RT Group Policy can be used to manage devices that run Windows RT. By default, the Group Policy Client service was disabled on Windows RT devices and must be enabled and configured to start automatically using the Services snap-in. Additionally, there were lots of new policy settings and preferences added to Group Policy in Windows Server 2012, including settings and preferences for Internet Explorer 10 and many other Windows components and capabilities. As far as enhancements in Windows Server 2012 R2 go, this time around it’s more of a fine-tuning of Group Policy capabilities rather than a lot of new functionality. Let’s examine some of the changes now. Group Policy caching One of the key enhancements in Windows Server 2012 R2 is policy caching, which can significantly reduce the amount of time it takes to process Group Policy on a client. Policy caching works by having the client download the policy from a domain controller and save a copy of the policy to a local store on the client. Then, when the next Group Policy processing occurs, the client can apply the policy cached in the local store instead of having to download the policy again from the network. By speeding up Group Policy processing, policy caching can shorten boot times for clients. This can be especially helpful in scenarios where the network connection experiences latency or is connecting from off-premises over the Internet, for example, in a DirectAccess scenario. Note that policy caching only works when Group Policy is running in synchronous mode. Policy caching is disabled by default in Windows Server 2012 R2. To enable and configure policy caching, configure the following policy setting named Enable Group Policy Caching For Servers as shown in Figure 7-1. This policy setting can be found under: Computer Configuration\Policies\Administrative Templates\System\Group Policy

Group Policy Preferences and IPv6 CHAPTER 7 139 FIGURE 7-1 The new Enable Group Policy Caching For Servers policy setting. Group Policy Preferences and IPv6 Another important area where Group Policy has been enhanced in Windows Server 2012 R2 is in regards to Internet Protocol version 6 (IPv6) support. An increasingly important part of the job of the Windows Server administrator is to prepare the organization’s network for migration to IPv6. The reasons for this include the exponential growth of the Internet, the proliferation of mobile devices that need to be able to connect to the corporate network, and the exhaustion of the IPv4 address space. Windows Server 2012 included a number of new IPv6 capabilities such as built-in support for NAT64/DNS64 when implementing DirectAccess, new Windows PowerShell cmdlets that supersede the Netsh.exe command-line utility of earlier Windows versions, and improved Internet connectivity by marking well-known IPv6 Internet resources Windows can’t reach as unreachable so that in the future only IPv4 is used for connecting to them.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
