Open a command window on the Vista box and try to ping by both IP and
hostname. If pinging by hostname fails, then you have a DNS issue,
not a php issue. In that case, I'd suggest heading over to
microsoft.public.* and asking in a Vista group.

If pining by hostname works, perhaps it is the port that is blocked?
Check the settings in the Vista box's firewall.
