Modify the DHCP range for ICS on XP

[uma]

Hi,

I am using a Win XP Sp1 machine.
If I enable ICS on a PC connected to a network that uses 192.168.0.*
range then I get the following error:
" A LAN connection is already configured with the IP address that is
required for automatic IP addressing".

Unfortunately I cannot change the address range or address of the
router to which my PC is connected.

o Is there any way of modifying the address range on win xp so that
local DHCP server uses this new address range.
o Or else is there any way of enabling the pass through mechanism for
the local DHCP server so that the main network DHCP server will assign
the IP address to the private network. This method would prevent the
address range conflict.

This is very much required for my project.

Please let me know.

Thanks in advance.

Modify the info on the DHCP server, not the XP machine.

If you have a router why do you want to use ICS??

You can get ICS to use a different range. However, this is an
unsupported configuration, not tested or suggested by Microsoft. It
might cause networking problems on the host computer, so make a system
restore point before doing it:

1. Temporarily assign a static IP address to the network connection
that you want to share, using an address that isn't in 192.168.0.x.

2. Enable ICS on that network connection.

3. Manually change the IP address of the LAN (home network) connection
to a different subnet, such as 192.168.1.x.

4. Restore the proper IP address for the shared network connection.

This unsupported configuration will automatically disable the DHCP
server that normally runs on the ICS host. You'll have to assign
static IP addresses to all of the ICS clients.

If you have any alternative to this configuration, I recommend using
the alternative.
