Cron doesn’t seem to work using WAMP/Vista/IPv6/etc, why?
From the looks of it WAMP isn’t listening on ::1 (IPv6 localhost) which is what the the cron service will try to connect to (localhost == ::1).
There are a few options:
Disable IPv6 (some Docs here: http://www.ipv6day.org/action.php?n=En.Configuration- WindowsVista), not really recommended.
Change the Juassi-Blog domain from localhost to 127.0.0.1 (or another domain name that has an IPv4 only address)
Enable IPv6 on WAMP
