- safe mode
A startup option that starts Windows Server 2003 with the basic drivers for the mouse, video, monitor, mass storage, and keyboard.
- SDOU
Group Policy inheritance in Windows 2003 works according to the hierarchy of site domain OU, or - Secure Sockets Layer (SSL)
SSL is used with HTTP to encrypt all traffic between the browser and the web server.
- security configuration and analysis
A tool that compares the security settings of a computer to those of a template, shows the results, and resolves any discrepancies that were revealed by the analysis. The tool allows you to perform comparisons with either the standard templates, or custom templates that you have created.
- security descriptor
The access-control information that is assigned to every object.
- security log
The log in Event Viewer that contains events relating to security and auditing.
- session directory
A service that creates a database on a server that contains a record of the current sessions being hosted by a load-balanced cluster of Windows Server 2003 Terminal Servers. This database indexes the sessions by username instead of IP address. The username is used to look up the location of a disconnected session when the user is trying to log on to the Terminal Services server again. After it is determined which server is hosting the session that the user was disconnected from, his or her logon is routed to that server.
- simple volume
The equivalent of a partition on a basic disk.
- soft limit
In disk quotas, when a soft limit is reached, a warning is issued, but the user is still allowed to save files.
- Software Update Service (SUS)
SUS is a service installed on an internal Windows 2000 or Windows Server 2003 server that can download all critical updates as they are posted to Windows Update. The client computers and servers can be configured through Group Policy or the Registry to contact the internal SUS server for updates, instead of going out over the Internet to the Microsoft servers. SUS is basically an internal version of the Windows Update service, with the exception that the network administrator has the option to control which updates get downloaded from Microsoft and which ones get installed on the computers in the environment. Microsoft is withdrawing all support on December 6, 2006. SUS has been replaced by Windows Server Update Services (WSUS).
- spanned volume
A spanned volume takes various amounts of disk space from 2 to 32 physical disks to create one large volume. Spanned volumes provide no fault tolerance; they can be more prone to failure than other types of volumes because if any one disk should fail, the entire set is lost. The advantage of a spanned volume is that you can quickly add more storage space.
- standalone server
A server that is not a member of a domain. It can be the only machine used, or it can be part of a Workgroup to provide distributed storage of files and printers.
- striped volume
A striped volume writes data to 2 to 32 physical disks in 64KB sequential stripes. The first stripe is written to the first disk, the second stripe is written to the second disk, and so forth. Striped volumes, also known as RAID-0, provide no fault tolerance. The advantage provided by using a striped volume lies in the overall disk I/O performance increase of the computer because the total disk I/O is split among all the disks in the volume.
- system file checker
The System File Checker (SFC.EXE) is used to verify that the protected system files have not been overwritten.
- system monitor
Used to track the performance of your Windows Server 2003 server.
- system partition
On an Intel-based system, the system partition contains the BOOT.INI, NtdETECT.COM, and NTLDR files. These files tell the server how to start the operating system. The system partition is also known as the active partition.
- system state
A collection of data that contains the operating system configuration of the server.
