Windows Server Essentials (formerly Windows Small Business Server or SBS) is an integrated server suite from Microsoft designed for running network infrastructure (both intranet management and Internet access) of small and midsize businesses having no more than 25 users or 50 devices. Application server technologies are tightly integrated to provide, e.g., the Remote Web Workplace, and offer management benefits such as integrated setup, enhanced monitoring, a unified management console, and remote access. Since the release of SBS 2003, the same service packs as those for Windows Server or other server products can be used to update the OS. == Editions == Windows Server 2012 R2 Essentials is the latest version of Windows Server Essentials (formerly Windows Small Business Server Essentials). Older versions: Windows Server is available in Essentials, Standard, and Premium editions. Essentials is a scaled down version for 1 to 25 users, both the other editions are based on the Windows Server codebase and include Microsoft Exchange Server mail server, Internet Information Services (IIS) web server, Windows SharePoint Services for collaboration, Microsoft Outlook 2003 email client (not included in 2008), Routing and Remote Access Service (RRAS), Windows Server Update Services for update management across the network, and a Fax server. Up to SBS 2003, the Premium edition also included Microsoft SQL Server, Microsoft Internet Security and Acceleration Server and Microsoft Office FrontPage 2003. SBS 2008 Premium edition will not include ISA Server but will include a Windows Server 2008 license and SQL Server 2008 for running on a second server. Those upgrading to SBS 2008 Premium edition via Software Assurance will be compensated with a free license for the latest version of ISA Server. The version of Windows Server that is part of Small Business Server 2008 and Essential Business Server 2008, known as Windows Server 2008 for Windows Essential Server Solutions (WinWESS) (also known as ''Windows Server 2008 Standard FE'') is available outside the product suite, supporting a maximum of 15 Client Access Licenses. Initially, Small Business Server was marketed as an edition of Microsoft BackOffice Server. When Windows 2000 was released, it was marketed as Microsoft Small Business Server 2000, and finally was rebranded as a member of the Windows Server 2003 family. In December 2008, Microsoft also introduced a Windows Essential Business Server product aimed at medium-sized businesses, but this was discontinued in June 2010 due to low demand. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Windows Server Essentials」の詳細全文を読む スポンサード リンク
