Changing Windows 7 ICS IP

When Internet Connection Sharing (ICS) is enabled in Windows 7, the local IP address of the computer becomes 192.168.0.1. However, that address isn't locked. I was able to change it to 192.168.1.1 in the usual way (in "Internet Protocol Version 4" properties in the "Local Area Connection" properties.) After this change, DHCP doesn't work right, but NAT works perfectly. So, ICS can be used as an emergency replacement for a router when all the computers have statically assigned IP addresses.
