Many new functions have been introduced to enable Windows Sockets 2 applications to take advantage of IPv6, including the getaddrinfo and getnameinfo functions. Skip to main content.

Standard DCH. Since enabling IPV6 on my modem, I have had several windows services frequently stop working.
As soon as I disable IPV6 on my modem and reboot my Win7 machines, the services no longer crash and the computer works correctly, although I obviously can't access IPV6 sites over the internet. To reproduce the problem, I do not need to change any settings in Win7. I do no disable IPV6 on the win7 machines in addition to the modem to stop the problem. Despite the modem no longer assigning an ipv6 address, when I check ipconfig, I see my links still have a "link-local ipv6 address", and this does not cause the windows services to crash.
If I re-enable ipv6 on my modem and reboot my win7 machine without changing any configuration options, several windows services start crashing again. This happens on both Win7 laptops I have at home, but I also have a Windows Vista and a linux machine which do not show any problems when IPV6 is enabled. You might have noticed that even the Windows Event Log service is one that keeps crashing when I have a IPV6 address, so I had to manually start it in order to view the event log.
I've got a new theory on what's going on. I noticed that all of the services I listed above run under the same PID, so if any one of them crashes, then all the rest get taken out too. Still, I think Microsoft needs to fix a few things. Firstly, a bad DHCP response shouldn't crash the dhcp service, assuming that's the problem. That's what input validation is for.
Secondly, the whole point of different processes is that one process can not adversely affect other processes. Otherwise we may as well run everything as separate threads under a single process. Even web browsers are moving away from threads to separate processes, so flash crashing doesn't kill the browser too.
So why are multiple windows services running under the same process? It's stupid that the event log and audio service crash because of something completely unrelated. I agree that IPv6 isn't mature on consumer devices and that it's not unexpected to have problems. However, Windows' IP stack and dhcp client service should be pretty mature and should not be crashing, in my opinion. In fact, it wasn't crashing on the older operating system, Visa, only on the newer one Win7, so it would appear that Microsoft made changes which introduced bugs.
I found that after a week of running the beta firmware on the modem with ipv6 disabled so ipv4 only , I started getting the same problem again, so it does not appear to be ipv6 specific. I've had to downgrade to the ipv4 only, stable firmware on my modem.
