Advanced Server con02.html Managing Services

Managing Services

Using the Services command in Server Manager, you can start and stop each of the services available on the computer, determine whether a service starts automatically when the system starts, and control some service startup parameters.

You can use the service startup dialog box to configure when and how a service is started, and optionally, to specify the user account that the service will use to log on. By default, most services log on using a special system account. (Of the services provided with Advanced Server, only the Directory Replicator service logs on using a specific user account.)

When a user account other than the system account is used to log on a service, that user account must have the Password Never Expires option selected.

Permission Required to Configure Server Startup
To configure service startup you must be logged on to a user account that is a member of the Administrators local group.

The services provided with the system are shown in the following table:

Service

Description

Alerter

Notifies selected users and computers of administrative alerts that occur on this computer. Used by the Server and other services. (Starts by default.)

Computer Browser

Maintains an up-to-date list of computers, and provides the list to applications when requested. Provides the computer lists displayed in the Select Computer and Select Domain dialog boxes, and in the main Server Manager window. (Starts by default.)

Directory Replicator

Replicates directories and the files in those directories, between computers.

EventLog

Records system, security, and application events in the event logs, and enables remote access to those logs. Starts by default. Cannot be stopped from Server Manager; stops together with the Server service.

Net Logon

Verifies the user name and password of each person who attempts to log on to the network or gain access to the server. Starts by default. (Service can be paused.)

Netrun

Lets users run UNIX system applications on a server from their own workstations. (Service can be paused.)

NvAlert

Allows a server to report error and status information to an IBM NetView network.

Remoteboot

Enables users at networked workstations to boot workstations with MS OS/2 or MS-DOS software. This is a separately-installable package.

Server

Provides file, print, and named pipe sharing, and support for remote procedure calls. Starts by default. (Service can be paused.)

SNMP

Provides applications programming interfaces (APIs) which allow development of third-party Management Information Bases (MIBs) and SNMP-based management programs. This is a separately-installable package.

Time Source

Identifies a server as the time source for a domain. Other computers synchronize their clocks with the time server.

Windows Internet Name Service (WINS)

Provides a Windows NT compatible, replicated, dynamic database for registering and querying NetBIOS computer name-to-IP address mappings in a routed network environment.

How Advanced Server Works With LAN Manager

Advanced Server integrates well with existing network systems, including Windows NT and LAN Manager. Advanced Server provides the software you need to establish communication between your computers running Advanced Server and other network computers and resources. However, because so many choices of protocols and services exist, you need to know your organization’s requirements before installing Advanced Server.

For two computers to communicate on a network, they must share at least one network protocol. Before installing Advanced Server, you will need to know the requirements of your organization.
