I have a 13" Macbook running Snow Leopard 10.6.6 which is unable to go to any URL on either my office or hotel networks.
I have no proxy or firewall enabled on the computer - and have connected to both networks in the past without issue.
If I ping google.com, it responds with 'cannot resolve google.com, unknown host' - however if I ping the IP it responds fine. I can also visit the IP in my browser and it goes to the page successfully.
I have rebooted, flushed my cache in several ways, tried to use Google's DNS (22.214.171.124, 126.96.36.199) all to no avail.
Any advice would be super!
