it requested. The DHCP module provides two settings for influencing the
period of validity:
̈ Maximum lease time in minutes
Here you can enter the maximum period of validity that the DHCP server
assigns a host.
If a host requests a validity that exceeds the maximum length, this will
nevertheless be the maximum available validity!
The default setting is 6000 minutes (approx. 4 days).
̈ Default lease time in minutes
Here you can enter the period of validity that is assigned if the host makes
no request. The default setting is 500 minutes (approx. 8 hours).
Precedence for the DHCP server—request assignment
In the default configuration, almost all the settings in the Windows network
environment are selected in such a way that the necessary parameters are
requested via DHCP. Check the settings by clicking Start ̈ Settings ̈ Con-
trol Panel ̈ Network. Select the TCP/IP entry for your network adapter and
open Properties.
Check the various tabs for special entries, such as for the IP address or the
standard gateway. If you would like all of the values to be assigned by the
DHCP server, simply delete the corresponding entries.
On the 'WINS configuration' tab, the 'Use DHCP for WINS Resolution' option
must also be selected if you want to use Windows networks over IP with name
resolution using NBNS servers. In this case, the DHCP server must also have
an NBNS entry.
Priority for computer—overwriting an assignment
If a computer uses parameters other than those assigned to it (e.g. a different
default gateway), these parameters must be set directly on the workstation
computer. The computer then ignores the corresponding parameters assigned
to it by the DHCP server.
Under Windows 98, this is accomplished through the properties of the Net-
work Neighbourhood.
Click Start / Settings / Control Panel / Network. Select the 'TCP/IP' entry
for your network adapter and open Properties.
You can now enter the desired values by selecting the various tabs.
