Windows Server 2012, formerly codenamed Windows Server 8, is the current release of Windows Server. It is the server version of Windows 8 and the successor to Windows Server 2008 R2.
features of Windows Server 2012.
1) User interface.
The operating system, like Windows 8, uses the Metro UI unless installed in Server Core mode. Windows PowerShell in this version has over 2300 commandlets, compared with around 200 in Windows Server 2008 R2. There is also command auto-completion.
2) Task Manager
Windows 8 and Windows Server 2012 include a new version of Windows Task Manager together with the old version. In the new version the tabs are hidden by default showing applications only. In the new Processes tab, the processes are displayed in varying shades of yellow, with darker shades representing heavier resource use.
3) Installation options
Unlike its predecessor, Windows Server 2012 can switch between "Server Core" and the "Server with a GUI" installation options without a full reinstallation. Server Core is now the recommended configuration. There is also a new third installation option that allows some GUI programs such as MMC and Server Manager to run, but without Internet Explorer, Windows Explorer or the new desktop and shell.
4) IP address management (IPAM)
Windows Server 2012 has an IPAM role for discovering, monitoring, auditing, and managing the IP address space used on a corporate network. IPAM provides for administration and monitoring of servers running Dynamic Host Configuration Protocol (DHCP) and Domain Name Service (DNS). IPAM includes components for:
a) Custom IP address space display, reporting, and management.
b) Audit of server configuration changes and tracking of IP address usage.
c) Monitoring and management of DHCP and DNS services.
5) Active Directory
Windows Server 2012 has a number of changes to Active Directory from the version shipped with Windows Server 2008 R2. The Active Directory Domain Services installation wizard has been replaced by a new section in Server Manager, and the Active Directory Administrative Center has been enhanced. A GUI has been added to the Active Directory Recycle Bin. Password policies can differ more easily within the same domain. Active Directory in Windows Server 2012 is now aware of any changes resulting from virtualization, and virtualized domain controllers can be safely cloned. Upgrades of the domain functional level to Windows Server 2012 are simplified; it can be performed entirely in Server Manager. Active Directory Federation Services is no longer required to be downloaded when installed as a role, and claims which can be used by the Active Directory Federation Services have been introduced into the Kerberos token. Windows Powershell commands used by Active Directory Administrative Center can be viewed in a "Powershell History Viewer".
6) Hyper-V
Windows Server 2012, along with Windows 8, includes a new version of Hyper-V, as presented at the Microsoft Build Event. Many new features have been added to Hyper-V, including network virtualization, multi-tenancy, storage resource pools, cross-premise connectivity, and cloud backup. Additionally, many of the former restrictions on resource consumption have been greatly lifted. Each virtual machine in this version of Hyper-V can access up to 64 virtual processors, up to 512 gigabytes of random-access memory, and up to 64 terabytes of virtual disk space per virtual hard disk (using a new .vhdx format). Up to 1024 virtual machines can be active per host, and up to 4000 can be active per failover cluster. The version of Hyper-V shipped with the client version of Windows 8 requires a processor that supports SLAT and for SLAT to be turned on, while the version in Windows Server 2012 only requires it if the RemoteFX role is installed.
7) IIS 8.0
