You can chose which interface to use:-
http://support.microsoft.com/kb/894564

The only entries that are particularly relevant
are the top four.

The top two determine which interfaces are used for
traffic sent to your router, the next two are for
local traffic to PCs on your local network.
In both cases interface 192.168.1.101
is being used since the metric is 20 which is better
than 25.

Just ignore the rest, it is only there to confuse you:)
