Windows Server Essentials

Windows Server Essentials (formerly Small Business Server or SBS) is an integrated server suite from Microsoft for businesses with no more than 25 users or 50 devices. It includes Windows Server, Exchange Server, Windows SharePoint Services, and Microsoft Outlook. Application server technologies are tightly integrated to provide and offer management benefits such as integrated setup, enhanced monitoring, Remote Web Workplace, a unified management console, and remote access.
Starting with Windows Server Essentials 2022, this product is only available through OEM providers. This product offers the same licensing terms and restrictions regarding the number of users/devices and cores; however, it also offers the same features as Windows Server Standard 2022.
History
As Small Business Server
Initially, Microsoft marketed the Small Business Server (SBS) an edition of Microsoft BackOffice Server. With the release of Windows 2000, however, Microsoft spun off Small Business Server 2000 as a separate offering. Until this point, the Premium editions of SBS included SQL Server, ISA Server, and FrontPage. SBS 2003 and later all bear the "Windows" brand and are editions of Windows Server.
SBS 2008 came with an edition of Windows Server 2008 bears the name Windows Server 2008 for Windows Essential Server Solutions ("WinWESS"), also known as Windows Server 2008 Standard FE. This edition of Windows Server 2008 is available outside the product suite, supporting a maximum of 15 Client Access Licenses. SBS 2008 Premium edition does not include ISA Server but includes SQL Server 2008. Those upgrading to SBS 2008 Premium edition via Software Assurance were compensated with a free license for the latest version of ISA Server. 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.
SBS 2011 was available in Essentials, Standard, and Premium editions. The Essentials edition is a scaled down version for 1 to 25 users; the other editions are based on the Windows Server codebase and include Exchange Server, Windows SharePoint Services, and Microsoft Outlook in addition to what comes with Windows Server.
As Windows Server Essentials
Starting with Windows Server 2012, Microsoft renamed SBS to Windows Server Essentials. Four versions of Windows Server Essentials were released along with their Windows Server siblings: 2012, 2012 R2, 2016, and 2019. Windows Server 2019 Essentials removed many features found in previous versions of Windows Server Essentials because the "Windows Server Essentials Experience" role was not included in any of the Windows Server 2019 SKUs. This includes Essentials Connector, Client PC Backup, Office 365 integration, Remote Web Access, and the Windows Server Essentials Dashboard.
Discontinuation
In September 2018, the Windows Server hinted that Windows Server Essentials 2019 might be the last version of this product. Following the release of Windows Server 2022, Microsoft announced that their Windows Server Essentials 2022 offering is merely a customized licensing scheme for the Standard edition of Windows Server 2022.
At the time of discontinuation, Microsoft offered the same software as part of its Microsoft 365 and Microsoft Azure plans.

The premium edition will contain a license for Windows Server 2008 and SQL Server 2008 Standard Edition, with the option to run SQL Server on either the main SBS server, or a second server. The premium edition will therefore be targeted at dual-server scenarios such as terminal services application sharing, line of business applications, edge security, secondary domain controllers, and virtualization. In addition to features present in previous versions, new features include:
A streamlined administration and management console that is designed around tasks to be accomplished rather than underlying technologies

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. One successor (code name "Aurora") supports a maximum of 25 users, does not include Exchange, SharePoint and Windows Server Update Services (WSUS), and is oriented to attach cloud services. 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 includes Exchange, SharePoint and WSUS.
Late in 2010, Microsoft announced the official branding for the 2011 wave: SBS "7" became "Windows Small Business Server 2011 Standard," and "Aurora" was christened "Windows Small Business Server 2011 Essentials." Whereas formerly, the premium edition of SBS was packaged as a superset of the standard edition, in the 2011 wave, it was be available as an add-on, containing standalone copies of SQL Server 2008 R2 and Windows Server 2008 R2. It could be added to either SBS 2011 Essentials or Standard.
In mid-December, Microsoft released SBS 2011 Standard to TechNet and MSDN subscribers for evaluation. Microsoft released SBS 2011 Standard to volume licensing customers in early January and as a trial in mid-January. SBS 2011 requires an Internet connection.
October 10, 2012 – Windows Server 2012 Essentials
In July 2012, Microsoft announced that there would not be another SBS product. Rather, Windows Server 2012 Essentials succeeded SBS Essentials. Windows Server 2012 Essentials does not include Microsoft Exchange Server, which is used for messaging and collaboration, including the ability to host email. Windows Server Essentials and its successors were designed for small businesses with up to 25 users and 50 devices.
September 9, 2013 – Windows Server 2012 R2 Essentials
October 12, 2016 – Windows Server 2016 Essentials
November 13, 2018 – Windows Server 2019 Essentials
Windows Server 2019 Essentials removed many features found in previous versions of Windows Server Essentials, including Remote Web Access, Essentials Connector, Client PC Backup, Office 365 integration and the Windows Server Essentials Dashboard. It is the last version of Windows Server Essentials.
Licensing
Normally, Microsoft licenses its on-premises server products on a per-seat or per-user basis, i.e., the licensing cost depends on how many users or computers use these products. Businesses that install them require to obtain client access licenses (CALs). Windows Server 2012 Essentials and later do not need any CALs. However, this has not always been the case. Earlier versions – Windows Small Business Server (SBS) – had their own types of CAL, and included the user CALs for Windows Server, Exchange Server, and eventually SQL Server. The SBS CALs cost more than the Windows Server CALs, but less than the sum of separate access licenses for the two or three servers.
Windows Small Business Server has the following design restrictions:
Only one computer in the domain can run SBS. The domain supports multiple servers (including additional domain controllers) running any other operating system, such as Windows Server, but only one SBS.
SBS must be the root of the Active Directory forest.
SBS cannot establish a trust relationship with any other domains or have sub-domains.
SBS is limited to 75 users or devices depending on the type of CAL.
SBS 2003 and earlier are limited to no more than 4 GB of RAM. SBS 2008 supports a maximum of 32GB. It requires a minimum of 4GB for installation, but needs more for performance.
SBS 2003 R2 and earlier are only available for the IA-32 (32-bit) architecture.
SBS 2008 is only available for the x86-64 architecture.
The SQL Server that comes with SBS 2008 is "SQL Server 2008 Standard Edition for Small Business.". It cannot be installed outside a network that has a domain controller, and must have fewer than 75 PCs or users (depending on the CAL.)
Remote Desktop Services on SBS is restricted to two simultaneous sessions. (Change from SBS 2000 policy) Terminal Services in application sharing mode needs to be run on a second server running a separately obtained copy of Windows Server.
To remove these restrictions and upgrade to regular editions of Windows Server, Exchange Server, SQL Server and ISA Server, there was a Windows Small Business Server 2003 R2 Transition Pack.
