DHCP server
Note
In PCS 7, the use of a DHCP server is only permitted with address reservation. All PC stations
must work with reserved addresses.
DNS / WINS server
The use of DNS for name resolution during domain configuration is mandatory.
Scenarios
Scenarios (examples) Domain (AD; Active Directory) Workgroup (WG)
New user is added. The new user is created centrally in the AD and
is then available immediately on all PC stations.
The new user must be added on each PC sta‐
tion.
User password is
changed.
The password is changed centrally in the AD. The password must be changed on each PC
station.
Add or replace computer The settings are applied automatically in ac‐
cordance with the group policies of the corre‐
sponding organizational unit.
The settings must be adapted locally on the PC
station.
Modify security settings The settings are changed centrally in the AD
and distributed by means of group policies.
All settings must be changed locally.
Microsoft Updates are to
be distributed.
The settings for the Microsoft Windows Soft‐
ware Update Service (WSUS) are made cen‐
trally in the domain.
The settings for the Microsoft Windows Soft‐
ware Update Service (WSUS) are made at
each PC station.
Devices are added (e.g.
printer, fax or scanner).
The devices are announced by AD. Devices not announced.
The information for connecting to the device
must be known.
The security settings can be made centrally for
each device.
Each user that uses the device must be created
locally at this PC station and log on with local
user information.
One user uses multiple
computers.
The user profile can be saved centrally.
This applies the settings to all PC stations at
logon.
The user has a local profile on each PC station.
If the profile is not saved centrally, every user
will have their own local profile.
The lists above are not weighted in terms of importance; you must determine which advantage
or disadvantage is the most significant for the PCS 7 plant in question.
Domain example
Changes can be made centrally, fast and conveniently in the domain structure. However, the
administration of a domain requires know-how, experience and additional work.
