Windows 2000 System Service Management

System Services is part of the operating system required for a feature to work on a base operating system, currently installed hardware devices, and other system services to provide network connectivity, error detection, security, and other basics. Operating system features. Through system services, administrators can manage services on local or remote computers (even remote computers running Windows NT 4.0). In Windows 2000, users can also set rescue actions taken when a service fails, creating user-defined names and descriptions for the service so that users can better identify them.

6.2.1 System Services Provided by Windows 2000

In Windows 2000 Server, the system provides users with many services and functions. Users can use these system services and system functions to perform the various operations required. For example, users can use system services for network connections, system error detection, and system security. Among them, the default services and their functions in Windows 2000 mainly include the following items:

? Alerter: Provides notifications to selected users or computers when an administrative alert such as a service failure occurs. The Alerter service is used by the Server service and requires the Messenger service to be running.

? ClipBook Server: Allows the process scrapbook on other computers to see the pages stored in the local scrapbook.

? Computer Browser: Tracks other computers on the network and provides information to the application when needed. Resource Manager and Network Neighborhood use the Computer Browser service.

? Directory Replicator: Copies files in directories and directories between computers on the network. This service is typically used when an administrator sets up a fault-tolerant environment or if a local copy of a remote server increases the performance of accessing files.

? Event Log: Stores applications, security, and system events in the event log. The event log viewer allows users to see events held by the Event Log service.

? Messenger: Send and receive messages sent by the system administrator or the Alerter service.

? Net Logon: Maintain security features such as user login and domain security. The Net Logon service also provides a mechanism for security files to be synchronized between servers in the domain.

? Network DDE: Provides network transport and security for DDE (Dynamic Data Exchange) sessions. Applications such as Word and Excel use the Network DDE service when sharing information over the network via DDE.

? Network DDE DSDM: The DDE Shared Database Manager (DSDM) handles the management of multiple DDE sessions and is used by the Network DDE service.

? NTLM Security Support Provider Plug and Play Locator: Provides Windows NT security for RPC applications that use a LAN Manager named pipe. This service is primarily used by older database server applications.

This service manages Windows NT and any plug-and-play BIOS support installed in the system.

? Remote Procedure Call (RPC): This service handles the directory of distributed applications such as database servers. The RPC application registers its availability using the RPC Locator service. This service is also used by clients to find compatible distributed RPC server applications.

? Remote Procedure Call (RPC) Service: The RPC Service provides communication functions for the RPC Locator and other RPC services.

? The Schedule:At command uses the Schedule service to run the application at the specified time and date.

? The Server: Server service manages file and print services for users connected to the local computer. It also manages named pipes and RPC support. When the Server service fails, the computer cannot access the user from the network.

? Spooler: Provides a print job spooling service. When a print job is sent to the printer, the Spooler service queues it behind the previous print job and waits for it to be sent to the printer. When a print job is ready to print, the Spooler service manages the flow of data from the print queue to the printer.

? UPS: Manages the functionality of an uninterruptible power supply connected to a computer. The UPS service handles communication between the UPS hardware and the UPS controller service on the computer. When the power supply is powered down, the UPS service sends a message to the UPS controller service that manages the power supply timing and handles any system shutdown functions.

? Workstation: The Workstation service manages network connections, drive letter mappings, printer connections, and other local application interactions with the network. Internet browsers use the Workstation service.

Without system services, computers don't have that much functionality, especially when system services are required to handle network functions.

In addition to the default system services, there are many other services that can be loaded and unloaded. They provide many of the features of the Windows 2000 operating system. For example, a software that runs as a system service and performs a system backup at a specified interval is purchased. When the backup software is installed, the system function of the scheduling function is automatically installed into the system service list. Users can even download a shareware that provides Telnet Server services from the Internet. This system service can be installed automatically or manually.

6.2.2 Starting and Stopping System Services

After Windows 2000 starts, the system will automatically start the required services. Open the "Start" menu and select "Programs"
