Re: ,So there's an online fix for not being able to get online?
So far a straight release and renew has not worked on any affected machines I have tried it on. However this has worked:
netsh winsock reset catalog
netsh int ipv4 reset reset.log
Also I have noticed that its not uncommon for the problem to only strike one network interface, so I have been able to successfully fix some laptops remotely via wifi even though their ethernet was borked.
