Network services are network operating application programs that run on the network. The network operating system installation program ensures that the user has a minimum of network services installed by default.
Some examples of services installed by the NT operating system, by default are:
- Alerter service - notifies selected users and computers, of administrative alerts that occur on the computer. As an example, an alerter service could be set to issue alerts whenever the used space of a hard disk exceeds a particular percentage of the total hard disk space.
- Event log service - records system, security and program events in the event log.
- Messenger service - sends and receives messages sent by administrators or by the alerter service.
- Other services such as the telephony service, which is used by programs to make data, fax, voice calls. These services have to be manually started by the user.
