ok i got one windows 2008 r2 with dhcp running with stateless mode disabled when setup dhcp with interface:

another csr1000 router with 2000:-1:-1::2 and can ping the dhcp server.

on the router I disabled the ND autoconfig just using these instruction:
http://mor-pah.net/2012/11/06/cisco-ios ... utoconfig/

Now csr100 interface is showing no more autoconfig:
GigabitEthernet2 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::215:5DFF:FE00:A54
No Virtual link-local address(es):
Global unicast address(es):
2000:FFFF:FFFF::10, subnet is 2000:FFFF:FFFF::/64
Joined group address(es):
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ICMP unreachables are sent
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds (using 30000)
ND advertised reachable time is 0 (unspecified)
ND advertised retransmit interval is 0 (unspecified)
ND router advertisements are sent every 200 seconds
ND router advertisements live for 1800 seconds
ND advertised default router preference is High
ND RAs are suppressed (all)
Hosts use DHCP to obtain routable addresses.
Hosts use DHCP to obtain other configuration.

3rd one is win7 client which is trying to get dhcpv6 from the win2008 dhcp pool but it is not working at all.
Everything is configured to receive dhcp ip6 from the dhcp server but on wireshark on server, i can only see bunch of unrecognized mac addresses with UDP, ICMPv6 with router solicitation packet. What else should I check??? What am I missin here? Thanks
