After uninstalling Symantec 360 network connectivity is no longer possible.
However I was able to connect via a virtual machine to the network and internet which was running inside this machine.
The ultimate cause of this was that the Symantec uninstall via the windows add remove programs process fails and leaves crap lying around.
If your Symantec subscribtion expired and you tried to remove it you will have a networking problem.
Download the removal tool and it cleans everything up.
