Resolution: Disabling IPv6 for your current network adapter might keep the error from showing up in the Event Viewer. Network and Sharing Center -> Change adapter settings -> Right mouse click on said network adapter -> Properties -> Uncheck 'Internet Protocol Version 6 (TCP/IPv6)' -> Press OK. You might have to reboot your computer for changes to take effect.

I disabled IPv6 in network properties and that has stopped the error in Event Viewer. Interestingly tho under NIC properties it still shows IPv4 as Internet and IPv6 as "Limited". So far I haven't noticed any side effects.

As far as my router not supporting IPv6 I have no idea if this is right or wrong. I've checked around some shops and noone has any idea on that but suggest that if it works on the same machine under Vista then the router must support it.

I tend to think that on this system the IPv6 is faulty in W7.
