Welcome to Hurricane Electric's Tunnelbroker.net forums!
I have noticed that on all my Windows 10 machines with the Anniversary Update, they no longer receive IPv6 DNS from DHCPv6 servers if network is configured for Stateless DHCP (Managed Flag unset, Other Flag Set in RA). They receive IPv6 information correctly if the network is configured for Stateful DHCP....It isn't just you. DNS servers aren't picked up after the AU via either RDNSS (which never worked) or stateless DHCPv6. Several others have made the same observation - something is clearly broken.
Thank you to the folks who have reached out to me with the logs and data. At this time, the product group is investigating further to determine root cause. I will update this thread as soon as I have some more information.Regards,Avatar of ARUDELLARUDELLMicrosoft (MSFT) 975 Point
So the fix for RS2 should be in the WIP builds, if not, should be in the next few build releases.In regards to the RS1 code fix, we are targeting Q1 of 2017 as long as testing/validation are successful. Once I have an exact date and KB article, I will update this thread again.For temporary workaround, would recommend to configure a startup script to do ipconfig /renew6 on the machines.
The fix should be expected to release with the March 20107 CU for 1607 clients if everything goes well.
