I have included some extra info below as this seems to be a rather large issue especially amongst Asus laptops.
I have uninstalled Deamon tools
updated sncduvc.SYS from the asus website here.
updated ASMMAP64.sys from asus (going to downloads tab, choosing Windows 7 64 bit and then going to ATK section) at this address.ASUSTeK Computer Inc.-Support-
When i tried to update the driver
for the Teredo Tunneling Pseudo-Interface it updated but told me there was an error but i was able to solve with this:
"if you can't seem to update your driver and have ZoneAlarm Security Suite,
you may want to check whether the Enable IPv6 box in Firewall | Main | Advanced is ticked or not
(the last box in the dialog) - if not, tick it and update the driver from the Device Manager."
Which seems to have done the trick.
Thanks very much for your help.
