Managing Services
Most of the services start even when the user has not logged on to the system and
keep running in the background. Services keep running whether or not any user is
logged on to the system. Some services depend on other services and thus create
service dependencies. The Services console in the Administrative Tools utility
Control Panel allows you to manage services. You can start, stop, pause, or
resume any service, control the startup type, or configure how the system should
behave if any service fails.
The Services Console (Figure 2-20) provides an excellent means of system mainte-
nance. You can access the Services console in any of the following ways:
From the Services icon under Administrative Tools in the Control Panel.
From the Computer Management console. The Services node is located
under Services And Applications.
By creating a custom Microsoft Management Console (MMC) by adding the
Services snap-in.

Chapter 2: Exam 70-270 Study Guide
To access the properties pages of any service, right-click the service and click
Properties. The following configuration tabs are available:
General
The General tab of the Services properties dialog box displays the name of the
service and the path of the executable file that is run to start the service. You
can configure the startup type of the service as follows:
Automatic
The service starts when the system is started.
Manual
The service remains enabled but must be started manually from the
Services console.
Disabled
The service is disabled. It does not start automatically or manually until
it is enabled. It is a normal practice to disable unused services in the
system in order to improve system performance.
The lower half of the window shows the current status of the service that can
be started, stopped, or paused. You can also manually start a stopped service,
stop a running service, pause a running service, or resume a paused service
from the buttons provided for each purpose.
Log On
This tab displays the service account that is used to run the service. Services
that are started automatically by the operating system at startup use the Local
System Account. Some services use the Network System account. Other
services can be configured to use one of the user accounts specially created
for the service. Unless you know the details of the service account, you
should not change the Logon type of any service.
Recovery
The Recovery tab includes options that the system is given when the selected
service fails. If any of the services fail, the other services dependent on the
failed service also fail and an event is recorded in the system log. You can
configure the system response on first, second, and subsequent service fail-
ures in one of the following ways:
Take No Action
The system ignores the failure of the service. This is the system default.
Restart The Service
The system will attempt to restart the service automatically.
Run A Program
You can configure a program to run when the service fails. This program
is specified in the Run Program section of the window. This can be an
executable program or a command-line script.
Restart The Computer
The computer will reboot if this option is selected. This option should be
selected as a last resort.
