2.3.3 Replicator
The Replicator service allows specific files and directories to be copied automatically from
the export server to one or more of the specifically configured import servers (server and
clients with the Replicator service).
The Replicator service on the export server monitors the export directory, containing the
designated files and directories. If a file in the export directory is changed or directories
and/or files are added or deleted, the Replicator service updates these directories and files
under the import directories.
2.3.4 Netlogon
The netlogon service connects a specified server to a domain. This simplifies the adminis-
trator’s duties: within a domain a user account only needs to be managed and maintained
on one server. User accounts can be maintained on each server using the single system
image (SSI), the accounts is thus centrally managed and distributed.
The netlogon service ensures that there is an identical copy of the user account on the
primary domain controller and the backup domain controllers of the domain. The netlogon
service also processes the logon procedures of the clients.
If you are using the Netlogon service, the servers in a domain have several roles:
The netlogon service also provides connections to other domains with which a trust
relationship exists.
2.3.5 Timesource
This is a Advanced Server service which identifies a server as the time source for a domain.
Other servers can synchronize their clocks with the time source.
UNIX servers cannot synchronise their clocks using this service.
Server role Task
Primary Domain Controller Maintains and distributes the master copy of
the user account database, handles “logon”
requests.
Backup Domain Controller Receives a copy of the user account
database, handles “logon” requests.
