ICS Advanced Configuration
Installing ICS using the default values (like:
IP-address 192.168.0.1 for the ICS-host) works fine for a
home-network, but in an office setup, there is most often already
a range of IP-addresses defined, so there is a need to configure
ICS to use non-default IP-addresses .
There is no configuration window to define ICS-IP-addresses,
changes have to be made directly in the registry, and the
ICS-values are stored in:
key: IntranetInfo, value: "192.168.0.1,255.255.255.0"
To change the IP-address of the ICS-host, modify under "Settings\General"
the key for "IntranetInfo" (in my example to :
When changing the address of the ICS-host, you also need to
change the IP-address for all other systems on the network, so
the ICS-DHCP-server must also be configured for a new IP-address
range, under the key: "Addressing\Settings":
||In this example, I change the
DHCP-range also to 192.168.10.x,
intending to use the addresses 11 to 20.
||lets not forget, that we have to
IP-address in the Network configuration.
When re-starting the ICS-Clients, check their
TCP/IP-configuration with "WINIPCFG":
||If it still shows the original
assigned (192.168.0.x ), click on
the button "Release"
to instruct your
system to give up this IP-address and
to request a new IP-address from
||Now, there is no IP-address defined.
( IP-address 0.0.0.0 means: no IP-address assigned)
Restart your system.
||On my system, when I restarted, I got
new IP-address 192.168.10.1.
While the subnet 192.168.10.x is ok,
why did I get the address "1" ???
I had configured the range of IP-addresses
in the ICS-DHCP-server from 11 to 20 :
Seems to be a bug.
In an office setup with a Windows NT-server,
you will most probably have configured already a DHCP-server on the NT-server, so there is no need for the ICS-DHCP-server.
||On the Windows98 SE CD-ROM in the
\TOOLS\MTSUTIL\ICS, there are INF-files to
de-activate and re-activate the ICS-DHCP-server.
(use right-click to select the INSTALL-option)
There is also the text-file ICS.TXT
with some more
details on these INF-files:
It shows the registry entries for these functions, so you could
also use REGEDIT to make the modification manually:
key: "EnableDHCP", value : "1"
When disabling the ICS-DHCP-server, make sure that you either
configure manually all required TCP/IP-values on the ICS-Clients
or that the DHCP-server on the NT-server provides all required
