need to change the dhcp scope in my Internet Connection Sharing setup

[Gerry Voras]

I am using a win98se box with ICS installed as a router/NAT/firewall box to
isolate a small piece of my network. In the lab the thing works great --
the external nic gets a 10.10.0.0/24 address from the main network, and it
spits out a 192.168.0.0/24 to the internal network.

However, in production I might have a problem. The external network uses
192.168.0.0/24 addressing, the same as what ICS is going to use on the
internal side. This may or may not be a problem, but I want to forestall
this by changing the DHCP scope on the internal side to an RFC1918 class A
or B range instead. I'm personally wanting to use the range 172.16.0.0/24
so I know instantly what I'm looking at during troubleshooting. What do I
modify on the ICS box (registry, control panel settings, whatever) to make
this happen?

TIA...

This Microsoft Knowledge Base article has full details Gerry:

How to Change the IP Range for the ICS DHCP Service
http://support.microsoft.com/?id=230148

A small, nit-picky point: according to RFC1918, the private address
space 172.16.0.0 - 172.31.255.255 is a /12 (16 contiguous class B
network numbers), not a /24.

I was going to subnet the class B range into something more manageable.
