It happened to me once. I went to the sharing preferences. The computer's name had not been changed, but it could only be accessed at the new name:

User uploaded file

I clicked "edit" and then it showed up as the new name. I changed it back to the correct name:

User uploaded file


Then I restarted my computer (which may not be necessary). That fixed the problem and it hasn't happened since (knock on wood!).


When/If the problem becomes chronic, turning IPv6 off seems to work for some people. It a quick fix though, not a solution. By turning it off, you are also slowing down the transition from IPv4 to IPv6 as the new, more secure and faster standard protocol.


I've heard people blame routers. I have the latest version of Verizon's FiOS router and yet it happened to me too. So while you may have to upgrade your router for IPv6 to work, it will not solve this particular problem, which I believe is in OS X (Mountain Lion). I asked if the issue had been fixed with Mavericks but I never got an answer.

For most people it will be many years until they need to change to IPv6.


Several OSs and routers work better without IPv6.


I always turn IPv6 off.
