Advertise DNS over IPv6 to Windows 8

[Liinux]

I cannot get Windows 8 to accept an advertised DNS server, no matter what I do.

A tested iPhone and a tested Windows 7 laptop works fine, and Windows 8 gets its IPv6 address and gateway correctly, just not the dns server.

My setup:
OpenBSD router on a dynamic IPv4 connection, running: rtadv, route6d and wide-dhcpv6.

rtadvd.conf

em1:\
        :addr="my-prefix":prefixlen#64:raflags#64:

dhcp6s.conf

Code Select Expand

option domain-name-servers my-prefix::1;

dhcp6s in debug mode gives the following output when addressing Windows 8's request.

As I said, other clients seems to work fine. Is this a Windows 8 bug, or a new default that I need to address?

Thanks in advance for your time!

I can't get Windows 8 to take DNS via DHCPv6, either.  It was working fine on Windows 7.

perhaps it's a bit too late to answer this question, but I've also experienced this issue and the only way to fix it was to reset the ipv6 interface using the netsh in an admin command prompt and the rebooting the machine:
netsh interface ipv6 reset
