I have two Windows Server 2008 SP2 x86 domain controllers. Both have statically assigned IPv6 addresses. The first DC is also running DHCP Server v4/v6. DNS has been configured to listen in on the IPv4 and v6 static addresses.
The odd thing is both DCs are also getting DHCPv6 addresses, and those addresses appear in both DHCP v6 and DNS (as AAAA records). Even after assigning them static IPv6 addresses, how can I make sure they aren't picking up DHCPv6 addresses from the first domain controller?
Also, each client is getting a proper IPv6 address from the DHCPv6 service. It is listing the IPv6 DNS address assigned before the IPv4 addresses (which is fine). However, when I do an nslookup, it connects to server "UnKnown" at that IPv6 address and and queries come back with "server not responding". Switching to the IPv4 address works just fine in nslookup.
The servers are not firewalled and are listening for DNS on their statically assigned IPv6 addresses.
