Patch and Update Management with Update Services
Windows SBS 2003 R2 Update Services is a new feature of Windows SBS 2003 R2, which provides centralized patch and update management for computers that are on the Windows SBS 2003 R2 network and that are running one of the Windows operating systems that support Microsoft Update.
By using the Update Services snap-in in the familiar Server Management Console, you can help protect the Windows SBS network by keeping Windows–based computers on the network up-to-date with the latest Microsoft software updates.
Increased Mailbox Size Limits with Exchange Server 2003 SP2
Exchange Server 2003 SP2 includes several enhancements to the Exchange Server 2003 messaging environment, including an increase in the mailbox store size limit. Exchange Server 2003 Standard Edition has a maximum mailbox store size limit of 16 GB. But SP 2 for Exchange Server 2003 automatically increases the mailbox storage limit from 16 GB to 18 GB, and you can manually adjust that limit up to 75 GB.

SQL Server 2005
Windows SBS 2003 R2 Premium Edition includes SQL Server 2005 Workgroup Edition. You can install SQL Server 2005 Workgroup Edition as your database for a business application. Additionally, you can upgrade the instance of Microsoft SQL Server Desktop Engine (Windows) (MSDE) used by Microsoft Windows SharePoint® Services if you want to be able to search document libraries on your company's internal Web site.
Expanded CAL Rights
New with Windows SBS 2003 R2, Windows SBS CALs give you the right to expanded access. Previously, a Windows SBS CAL covered access only to the server running Windows SBS as well as to any additional servers on the network running Windows. However, a Windows SBS CAL did not cover access to Exchange Server 2003 or SQL Server 2000 on additional servers and required the purchase of additional licenses.
With Windows SBS 2003 R2, Windows SBS CALs give you the right to expanded access. If you add servers running Exchange Server 2003 or SQL Server 2005 Workgroup Edition to the Windows SBS network, the Windows SBS CAL now covers access to Exchange Server 2003 and SQL Server 2005 on additional servers as well.
