This is not correct. The shared network connection (Ethernet adapter
on PC A) must not have an address in the 192.168.0.x range. The
192.168.1.x address that it's getting from the ADSL modem/router is
fine.

It's the home network connection (wireless adapter on PC A) that ICS
automatically sets to 192.168.0.1. As you note, Peter, ICS doesn't
support changing that address.
