[arch-general] Problem with Transient resolver failure with pacman (Don't Panic)

I have Archlinux running on one machine with no problems, but the install was done a while back. I've just installed it on a new machine that I've built, but am having problems running pacman -Sy. The network setup is ok. I use static IP addresses, and everything is correctly set. /etc/resolv.conf has the correct nameserver set, and the gateway 192.168.0.1 in /etc/rc.conf is active by removing the "!". Running pacman -Sy though is constantly giving me a "Transient resolver failure" . Pacman -Sy is trying every mirror on the planet, and must have worked it's way through at least 30 up to now. There must be some setting that I havn't got right. Any suggestions would be most definately gratefully received. Nigel.
