Hi Ken,
Thanks for all your advice.
Still no joy, so in the end I partitioned my hard drive, put all data to one part and reinstalled Vista. It took best part of a day, however, I now have internet connection. Having searched around the net for problems involving
“Reseting Echo Request, failed. Access is denied" &
“"the operation failed as no adapter is in the state permissible for this operation".”
I am yet to see anyone who resolved it without a re-install. I think the registry or winsock had become corrunpted. I had spent several days trying to repair it without any luck.
Thanks again
