A brief description of the various services of Windows 2000

  Alerter (Alarm Service): Alerts the system administrator when there is a problem in the LAN, which can be set to "disabled" or "manual" for normal users.

  Application Management (application management): Win2K introduced a new, effective software management solution based on the msi file format (application installation information package file) - application management component service, it Not only the installation and deletion of management software, but also the use of this service to modify, repair existing applications, monitor file recovery and eliminate basic failures through recovery. However, when set to "disabled" does not seem to affect the installation and uninstallation of software on a single machine, and the behavior of installing, repairing, and deleting based on the msi format is normal.

ClipBook: Review the scrapbook in the remote machine through the network dynamic data exchange service provided by Network DDE and Network DDE DSDM. It can be set to "disabled" for normal users.

Computer Browser: Maintains an up-to-date list of computers in My Network Places and notifies this list of requested programs. The normal user is set to: "Disabled" and the LAN user is set to: "Automatic".

  DHCP Client (Dynamic Host Configuration Protocol Client): DHCP is a TCP/IP service protocol that provides dynamic IP address allocation and management. As part of the network boot process, the HCP client system can Request and lease an IP address from the DHCP server. As a normal user, if you have connected to the Internet through dial-up, it is still good to keep it automatic, because our IP address on the Internet is dynamically assigned by the ISP. If the system does not apply to any network, you can set it to "disabled."

Distributed Link Tracking Client: DLTC can track the movement of files in NTFS volumes in the network domain and send notifications. The normal user is set to: "Disabled", and the LAN user (the hard disk has been formatted as NTFS) is set to "Automatic".

  DNS Client (Domain Name System Client): resolves the domain name to an IP address. It should be set to "Automatic" unless you are not connected to any network.

  Event Log: This service can record error messages sent by programs and systems. Although the log contains information that is helpful in diagnosing the problem, it may not work for the average user, so set it to "manual"! Remember the Dr. Watson tool mentioned earlier? There we can't decide whether to cancel the log file. By default it is always executed automatically, now you can choose. However, after I disabled the service in the test and restarted the system, it caused several problems that the network service could not be started, which made us unable to dial up. So if you have an Internet or LAN connection, we recommend that you do not disable it.

 Fax Service: The fax function supported in Win95 is now re-supported in Win2K and integrated better with the system. If you can't use it, set it to "disabled"!

  Indexing Service: Indexing Service can index the content and attributes of documents on local hard disk or shared network drive, and quickly locate the documents you need through Win2K's unique document filter. On the other hand, it greatly enhances the search capabilities of Win2K. On the one hand, index search consumes a lot of system resources. Microsoft recommends: only 64MB of memory, and more than 100,000 documents to be indexed, you should disable this service. In fact, in our test for 64MB memory system, even if the number of documents is far less than 100,000, the system resource consumption is very amazing, and the situation is not much better on the 128MB system, so we strongly recommend disabling it. .

  Internet Connection Sharing: Provides an Internet sharing connection for LAN computers. This service provides a shortcut for multiple networked computers to share a dial-up network to access the Internet. In the past, Win9X needed to use SYGATE, WinGATE and other agent software to achieve this function. Now this function has been directly supported by Win2K. It can be set to "disabled" for normal users.

  IPSEC Policy Agent: This proxy service allows IP security policies to encrypt packets transmitted between two computers, thereby preventing people who see it on the Internet from doing it. Change and decipher. IPSEC is an important defense method to protect internal networks, private networks, and external networks (Internet, Extranet) from attacks. Before using IPSEC, you must first define the way in which two computers trust each other and communicate securely. Please note: In Win2K, the "IP Security Policy Agent" is automatically started by default, and the "IP Security Policy" is not activated (we can be in "Network and Dial-up Connection" → "Your Dial-up Connection Properties" → "Network" Page → "Internet Protocol (TCP/IP)" Properties → "Advanced" → "Options" page under the "IP Security Mechanism" attribute). In this case, the general user can completely disable the proxy service.

  Messenger (message service): Send and receive services sent by the system administrator or by the Alerter service. Since the Alerter service needs to look for this service, this can be set to "manual" or "disabled" if Alerter has been banned.

  Net Logon (network login): Simply put is the option to verify login information on the LAN. Normal users can set it to "disabled" or "manual".

  NetMeeting Remote Desktop Sharing: This service allows users to remotely access Windows desktops through NetMeeting. This feature is generally not useful and can be set to "disabled". Network Connections: It manages all the objects in the Network and Dial-up Connections folder. Keep "manual" if you have any network connections, including Internet dial-up connections. Otherwise, if you disable it, the "Network and Dial-up Connection" will remain "manual". Otherwise, if you disable it, you will not see anything in the "Network and Dial-up Connections" folder, let alone create a new connection and dial-up Internet access, do not believe you give it a try.

  Network DDE (Network Dynamic Data Exchange) and Network DDE DSDM: Network Dynamic Data Exchange Service is a service that provides network transmission and security for DDE conversations. DDE (Dynamic Data Exchange) is a form of process communication that allows two or more programs that support DDE to exchange information and commands. It can be set to "disabled" for general users.

Plug and Play: Plug and Play is a set of specifications developed by INTEL that gives computers the ability to automatically detect and configure devices and install drivers. When it is changed, it can automatically notify the current device status of the program that uses the device. Keeping the service state "automatic" facilitates the management and maintenance of the device.

  Print Spooler: The purpose of this service is to save and manage multiple documents that are requested to be printed. After the printer is idle, the data is sent to the printer for processing. Users without any printing device are set to "disabled", otherwise set to "automatic". Please note: If you have the Fax Service enabled, you should keep it automatic, as the fax service relies on the operation of Print Spooler.

Remote Procedure Call (RPC): A messaging feature. It allows distributed applications (ie COM+ applications) to call available services on different computers on the network during remote management of the computer. It seems that we can disable it, but you may not know that there are many services that depend on its operation, such as: Fax Service, Network Connections, Telephony, etc., so keep it "automatic"!

Remote Registry Service: This service enables you to edit the registry on another computer. It is not necessary for ordinary stand-alone users to use this service.

  Run As Service (service running as a user): When you log in to the system as a general privilege user, you need to modify the system settings that can only be modified by the system administrator. This service provides a shortcut to log in as an administrator without rebooting the system. You only need to run the RunAs command at the command prompt to achieve the change. For general users, you can set it to "disabled" before you are familiar with the RunAs command usage.

  Smart Card and Smart Card Helper: These two services provide support for smart card devices, set it to "disabled".

  Task Scheduler: Do you remember the "planned tasks" in Win9X? Its role is the same in Win2K. It enables programs to run automatically at scheduled times, such as regular disk defragmentation. If you think it's in the way, it's a good idea to disable it. Why do you want to use unused resources to take up system resources?

  TCP /IP NetBIOS Helper Service (TCP /IP NetBIOS Support Service): This service can provide NetBIOS support on TCP /IP. As we mentioned earlier, NetBIOS is LAN-based, so it can be disabled as a general user accessing Internet resources unless your system is on a LAN.

  Telephony (telephone): Simply put, this service can provide the phone with the ability to dial the phone. If you use dial-up to connect to the Internet or connect to another computer over a telephone line, you should set it to Manual. Telnet: This service allows you to log in to the system from a remote computer and use the command line to operate this computer. This service is not important for general stand-alone users and can be set to "Manual" or "Disabled".

  Uninterruptible Power Supply: A service that manages the uninterruptible power supply (UPS) connected to a computer. Set to "Disabled" if you do not have a UPS device.

Windows Management Instrumentation and Windows Management Instrumentation Driver Extensions: WMI is the underlying management structure in Win2K that controls and monitors systems through a common set of interfaces. (such as viewing and changing system properties, setting user permissions, etc.). To speed up the system startup, we can set these two services to "manual" and use them automatically when needed after the system is started.
