The information in this page is based on the following Microsoft Guide:
Threats and Countermeasures: Security Settings in Windows Server 2003 and Windows XP - Version 2.0
The following sections describe the Windows Server 2003 and Windows XP services in alphabetical order. Services that are installed by default are included as well as additional services that can be added to the computer.
Note: If a service is not started, other services that depend on that service will also fail to start. Therefore, if you change the status of one service you may affect other seemingly unrelated services. Such dependencies exist for all of the services that are described in this section. To check the dependencies for a service, click the Dependencies tab of the service's properties dialog in the MMC Services snap-in.
