Umlauts and special characters are not permitted. The full stop is used as a separating mark between
the individual components of a FQDN and must therefore not appear as part of the computer name.
Computer names must begin with a letter.
Microsoft Windows accepts computer names with a maximum of 15 characters, so as a rule computer
names should be limited to 15 characters if there is any chance that Microsoft Windows will be used.
’IP’ tab
IP address
Fixed IP addresses for the host can be given here. If a network was selected on the General tab, the
IP address assigned to the host from the network will be shown here automatically. The IP addresses
shown here can still be changed at another time. A thin client needs a fixed IP address under all
circumstances.
Attention:
An IP address entered here (and in the LDAP directory) can be now be transmitted to the host via
DHCP. If no DHCP server is being used, the IP address can also be transferred to the host locally.
Attention:
If the IP addresses entered for a host are changed without the DNS zones being changed, they are
automatically changed in the computer object and — where they exist — in the DNS entries of the
forward and reverse lookup zones. If the IP address of the host was entered at other places as well,
these entries must be changed manually! For example, if the IP address was given in a DHCP boot
policy instead of the name of the boot server, this IP address will need to be changed manually by
editing the policy.
’DNS’ tab
This tab allows selection of the forward and reverse lookup zones in which the host is entered and
specification of a DNS alias. A fixed IP address is required for these entries, which must be entered
on the IP tab so that the DNS entries can be created automatically. No entries are created so long
as no zones have been selected. In order for a thin client to function correctly it requires a DNS entry
(Host record in the forward lookup zone).
More detailed information on the topic of DNS can be found in the Chapter 4.5.9.
Forward zone for DNS entry
A forward lookup zone for the host can be selected here. All the forward lookup zones entered in the
domain and their subcontainers are available for selection. In addition it is also necessary to select
one of the host’s IP addresses with which the host should be included in the forward lookup zone.
