Something to add to this topic:

I tried nmap on my own network like this and came up with a 192.168.0.*
number that wasn't one I had assigned (I assign manually). Repeated reboots
of everything found that same number when using Nmap. It was assigned, as it
turned out, to my ADSL modem which isn't a router, just a modem. I hadn't
ever assigned it anything and hadn't even given it any thought really. I use
ICS between my 2 x WinXP machines and 2 x 98SE machines on the network so
all can get on the net.

So, the original poster might consider interrogating his broadband modem (if
he has one).

Greg.
