Well, after diligence and testing... I've solved this. Windows 2008 DHPCv6 will not work reliably without having a static IPv6 address assigned to it.
I have not decided how I feel about that yet. From: Jason Gauthier Sent: Friday, July 09, 2010 3:12 PM To: NT System Admin Issues Subject: DHCPv6 Greetings, I'm struggling with an issue with DHCPv6. I'm using this, effectively, as stateless. I have a Cisco router set up to multicast router advertisements. It is doing so successfully, setting the options "Managed" to false, and "Other" to true. I have confirmed through network traces and Windows 7 DHCPv6 event logs that it is receiving the announcements, and setting the options correctly. This is working good! Now, here comes the part that I'm struggling with. Once the options are set, the client machine should (and does) poll for DHCPv6 options only. Again, I've confirmed though network traces that this is happening successfully. 15:03:45.012474 IP6 (hlim 1, next-header UDP (17) payload length: 110) fe80::188b:8ff9:305c:71a3.546 > ff02::1:2.547: [udp sum ok] dhcp6 solicit (xid=fd9725 (elapsed time 3100) (client ID hwaddr/time type 1 time 316484303 00155d320606) (IA_NA IAID:369104221 T1:0 T2:0) (Client FQDN) (vendor class) (option request DNS name DNS vendor-specific info Client FQDN). My DHPCv6 server (running netmon) can definitely see the multicast requests sent to FF02:0:0:0:0:0:2:1. However, it doesn't respond, acknowledge, or otherwise seem to care. Options 23 (DNS Recursive Name) and options 24 (Domain Search List) are set. I have done this on two different networks, two different DHCPv6 servers. Neither of them responds. Even the statistics do not count up that there was a solicit message. I am intending to open a ticket with MS, but sasupport seems to be non-functional for me at the moment. So, I thought I would ask here. All my clients are Windows 7/2008R2, and my two servers are 2008 R2. Thanks for reading.
