Microsoft said it plans to add most of the enhancements -- with some variations -- from the SAC releases into upcoming LTSC releases.Microsoft engineer David Cutler developed the kernel of Windows NT with the intent to provide speed, security and reliability that large organizations require in a server operating system.Windows NT had the ability to run on less costly x86 machines.The 32-bit operating system featured a hardware abstraction layer ( HAL ), which provided more system stability by blocking applications from direct access to system hardware.
Companies could use Advanced Server as a domain controller to store user and group rights. Other networking improvements allowed users on other non-Microsoft operating systems to access files and applications on the domain. This server OS was optimized to deliver services faster to users through its updated networking stack. Microsoft added more connectivity support for companies in a mixed environment with both Windows NT and NetWare servers to allow users to get services from each with a single credential. Microsoft expanded the networking protocol capabilities in this release to make network resources available to a wider array of non-Microsoft machines. This server OS also could walk administrators through various tasks, such as sharing a hard disk with a feature called Administrative Wizards. Active Directory lets administrators perform various tasks, such as virtual private network configuration, data encryption and granting access to file shares on networked computers. Microsoft hardened IIS, the web server feature, and disabled more default services to reduce exploit opportunities. Microsoft Windows Server License To UseOrganizations always need to buy a new Windows Server license to use the new server operating system, but R2 releases used the client access licenses ( CALs ) of the immediately preceding server version to eliminate the need to upgrade those licenses. Among the security improvements in this release was the Security Configuration Wizard, which let administrators apply consistent security policies to multiple machines. The company also updated Terminal Services functionality and rechristened it to Remote Desktop Services ( RDS ). Windows Server 2008 R2 also marked a change from a 32-bit server operating system to a 64-bit version. The company also made significant updates to the operating systems storage infrastructure and Hyper-V virtualization platform. Upon this release, PowerShell had 2,300 cmdlets available for management. The Standard and Datacenter editions had the same feature set, but a Standard license permitted organizations to run two virtual machines (VMs), while Datacenter permitted an unlimited number of VMs. Microsoft says Nano Server is 93 smaller than a full Windows Server deployment. In previous Windows Server versions, the Standard and Datacenter editions had the same feature set, but different license rights and use restrictions. SAC releases will come every six months -- one in the spring and one in the fall -- with mainstream support of just 18 months. Microsoft tailors the LTSC for companies that prefer the more traditional release cycle of two to three years between major feature updates with the typical five years of mainstream support followed by five years of extended support.
