Windows Server Essentials
|Stable release||2012 R2 / November 25, 2013|
|License||Commercial proprietary software|
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.
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.
Design and licensing considerations
Windows Small Business Server has its own type of Client Access License (CAL), that is different and costs slightly more than CALs for the usual editions of the Windows Server operating system. However, the SBS CAL encompasses the user CALs for Windows Server, Exchange Server and SQL Server, and hence is less expensive than buying all the other CALs individually.
Windows Small Business Server has the following design restrictions:
- Only one computer in the domain can be running Windows Small Business Server. That is not to say that the domain only supports a single server. The domain supports multiple servers (including additional domain controllers) running any other operating system, such as Windows Server Standard Edition.
- Windows Small Business Server must be the root of the Active Directory forest.
- Windows Small Business Server cannot trust any other domains. It cannot have any child domains.
- Windows Small Business Server is limited to 75 users or devices depending on which type of CAL (SBS 2008 FE supports a maximum of 15 CALs).
- All Windows Small Business Server versions up to SBS 2003 are limited to 4 GB of RAM. 2008 requires a minimum of 4GB for installation, it needs more for performance. 2008 supports a maximum of 32GB.
- Windows Small Business Server versions prior to Windows Small Business Server 2008 are only available for the x86 (32-bit) architecture.
- Windows Small Business Server 2008 is only available for the x86-64 (64-bit) architecture. This is due to the requirements of Exchange Server 2007, whose production version is 64-bit only. The 32-bit version of Exchange Server 2007 is only supported for testing and non-production scenarios.
- The SQL Server which comes with SBS 2008 is "SQL Server 2008 Standard Edition for Small Business.". It cannot be installed outside of a network that has a domain controller, and must have fewer than 75 PCs and/or users.
- Only the Remote Desktop for Administration mode is available because Small Business Server always runs on the domain controller, and only two simultaneous RDP sessions are allowed. (Change from SBS 2000 policy) Terminal Services in application sharing mode needs to be run on a second server on the network. This however is possible with SBS 2011 Premium add-on which includes a Windows Server 2008 license for running the second server.
- To remove these restrictions and upgrade to regular editions of Windows Server, Exchange Server, SQL Server and ISA Server, there is a Windows Small Business Server 2003 R2 Transition Pack.

- December 13, 2010 – Windows Small Business Server 2011
- Microsoft announced two successors to the SBS series during WPC 2010, both based on Windows Server 2008 R2.

The other successor (code name "SBS 7") is the more direct successor of SBS 2008, and continues to support a maximum of 75 users, and will continue to include the next generation on-premises versions of Exchange, SharePoint and Windows Server Update Services.
- Late in 2010, Microsoft announced the official branding for the 2011 wave. SBS "7" will be branded as Windows Small Business Server 2011 Standard, and "Aurora" will introduce a new edition to the SBS product line: Windows Small Business Server 2011 Essentials. Additionally, changes to the premium edition were announced. Whereas formerly, the premium edition of SBS was packaged as a superset of the standard edition, in the 2011 wave it will be available as an add-on edition, containing standalone copies of SQL Server 2008 R2 and Windows Server 2008 R2, and available to add onto either SBS 2011 Essentials or Standard.
