• #7: DHCP--Previous editions of Windows Server made it difficult to configure resilience for DHCP, since conflicting DHCP servers are not allowed. Describe old style dhcp with 80/20. Describe failover cluster, no more no less 2 servers, shared storage, one has to be unavailable.--PowerShell v3 introduces a whole family of cmdlets to configure DHCP in Windows Server 2012.  Employ PowerShell not only to install the DHCP server role, but also to configure the scope.--DHCP failover is now available as a built-in feature. Hot Standby and Load Sharing.==Failover - The active server responds to all client requests and the standby server does not respond to any client requests at all while operating in NORMAL state. When active server goes down, the standby server transitions into Communication Interrupted state and starts responding to the clients. Once the active server is up, the standby server retreats into standby mode and stops responding to clients. This facilitates failback of the clients back to the active server.==Load Balance mode, where the 2 DHCP servers compute a hash of the MAC address of the clients and decide whether to respond to the client or not.Load sharing option is ideal for situations where both DHCP servers in a failover relationship are located at the same physical site.  Whereas the hot standby option is better where you want a central backup to DHCP servers at a remote site
• #8: Group Policy is a great tool but testing it has sometimes been trying. Although Microsoft makes available the gpupdate tool, which forces a client to refresh its local and Active Directory-driven policies, there are still occasions when it can take more than an hour for a Group Policy change to become effectiveFrom within the Group Policy Management Console, you can right-click an Active Directory container then from the shortcut menu, choose Group Policy Update, you will be told how many computers will be affected by the operation. If you’ve selected a container with no computer objects, you will be told so. Once done you will get a status update so that you know exactly how the update turned out.
• #9: ==The new Resilient File System, ResFS for short, is designed to be more robust than NTFS against corruption or media failure – ResFSdoes not re-use the same disk blocks over during a write, so if it's interrupted, the original data will be intact.==CHKDSK is much faster and can even be run while disks are online. Sparse provisioning means that formatting new disks is vastly quicker, too – terabytes can be ready for use in seconds, especially if you are using hyper-V and it’s ability to use 64 TB disks==Automatic data deduplication– it scans disks and files and replaces duplicated data with links, so that the exact same contents take up much less space – I viewed a demo, where it saved 11GB on a disk containing three copies of a 5GB set of files. If you have an install of S12, you can copy the "ddpeval.exe" program from a WS2012 machine into \WINDOWS\SYSTEM32 on an older Windows Server and see how much space you'd save.==The fileserver component has had a major revamp. The wire protocol has been streamlined and lots of "chatter" removed to make it faster over slower connections. On local networks, it supports multiple connections – for instance, even in mid-copy, plugging in an additional Gigabit cable will result in the time remaining dropping sharply.Data StorageA virtual disk can be larger than the available space, a technique called thin provisioning, in which case you will need to add drives to the pool as it fills. Storage Spaces can be confusing, particularly with parity striping, but it does offer built-in scalable and resilient storage. You can even assign virtual disks to folders rather than drive letters
• #10: ==The biggest changes are around the hypervisor and various aspects of virtualization. This is the third release of Hyper-V – the moststabe version yet. Hosts, clusters and VMs all support industry-leading high-end specs and a swath of high-availability features. If you have a SAN, VMs now support virtual Fiber Channel ports for direct connections, and the fileserver role supports ODX for offloading operations onto SAN servers.==You don't need a SAN, though. VHDs can be stored on a file share, facilitating live migration between hosts even without a cluster, and the new Hyper-V Replica feature allows VMs to be replicated in the background between shared-nothing hosts, even across WAN links.==WS2012 also virtualizes storage and networking. VM networking now goes through a full managed virtual switch, allowing network connections to be virtualized – so for example IP addresses can be reassigned on the fly from a VM on one machine to another on a different host, reducing the need for complex VLAN configurations.The new storage pool system essentially brings full logical volume management to Windows, rivalling Sun's ZFS, with configurable mirroring and parity – so that all the storage attached or assigned to a server can be presented as a single pool, with flexible dynamic sub allocation.==Microsoft now recommends that all servers run virtualized – even Domain Controllers; the new "Generation ID" flag in Active Directory makes it simple to clone or roll-back a virtualized DC, which can then reconfigure itself appropriately. ==VDI and Terminal Server functionality are both much improved, with features such as server GPU acceleration – and emulation if one isn't available – and enhanced RemoteFX for touch interfaces and better support for operation over the public Internet. VDI images can be either pooled or personalized, or pooled images can have a personal disk attached for seamless, local-disk-performance roaming profiles.
• #11: SQL - Computers running Windows Server 2012 that connect to computers running SQL Server 6.5 (or earlier) will receive an error message.Server Message Block (SMB) - SMB.sys has been removed. The operating system now uses the Winsock Kernel (WSK) to provide the same functionality.Cluster.exe - Good old cluster.exe will be replaced by failover cluster powershellcmdlets. Cluster.exe won’t be installed by default but it is an optional component. 32 bits DLL resources are no longer supported also.Token Rings - Token ring network support is removed in Windows Server 2012, anybody using it??
• #12: Unlike the move a lot of people did from server 2003 to 2008 r2 that was 32bit to 64bit, necessitating migrations. 08r2 and s12 are both 64bit, so inplace upgrades become a viable option
• #13: CoreCommand PromptInstall, configure, uninstall server roles locally with PowerShellFrom your workstation (7 or 8) Install, configure, uninstall server roles remotely with Server Manager, Remote Server Admin Tools (RSAT) or PowerShellMMC not available locallyNo DesktopLimited Rolls (no remote desktop services)Can be converted to GUI
• #14: New for s12This basically provides a Server with GUI, but without installing Internet Explorer 10, Windows Explorer, the desktop, and the Start screen. Although you do get, Microsoft Management Console (MMC), Server Manager, and a subset of Control Panel. Minimal Server Interface requires 4 GB more disk space than Server Core alone. This can be converted to either Full GUI or Minimal Core.
• #15: Standard InterfaceWindows 8 like, no Store, Not able to use Store apps, but you are able to add the Desktop experienceInstall, configure, uninstall server roles locallyInstall, configure, uninstall server roles remotely with Server Manager, Remote Server Admin Tools (RSAT) or PowerShellCan be converted to server Core, Windows features, server roles, and GUI management tools that require a Server with a GUI installation will be uninstalled automatically
• #16: Credit for Box Art - Servers Plus is the UK’sLicensing in Windows Server 2012 has changed, and is now essentially a per-processor model. There are three editions. Foundation is a starter edition for OEMs that permits up to 15 users on a single processor box
• #17: Essentials is the closest thing to the abandoned Small Business Server line, though it is a lesser thing with a 25 user limit and no Exchange: you are expected to connect to the cloud-hosted Office 365 instead.
• #18: Standard allows up to two processors and up to two virtual instances.All Roles and features are available.
• #19: Datacenter allows up to two processors and unlimited virtual instances. If you have more than two processors, you buy additional licenses, so for an eight-processor box you would need four licenses for either Standard or Datacenter. Note that the limitation on virtual instances refers to licenses for Windows Server running on those instances. It is not a limitation on the number of virtual machines (VMs), so for example you could run unlimited Linux VMs on Standard Edition
• #20: Unlike the move a lot of people did from server 2003 to 2008 r2 that was 32bit to 64bit, necessitating migrations. 08r2 and s12 are both 64bit, so inplace upgrades become a viable option
