Vista machine cause XP machine to lose inet access

I had 2 XP machines hooked up to a router and dsl modem with internet
access.

I replaced one of the XP machines with a new Vista machine. Now both
XP and Vista machines are connected to the router.

Now when I shut down the vista machine, the XP machine will lose
internet access.

Anyone know what could be causing this ?

Thanks,

posting the results of ipconfig /all on both computers may help.
