IPv6 router advertisement not configurable on Windows 2008 and 2008 R2 servers.

hello networking experts,

i want configure windows server act publisher ipv6 domain prefix. according article configuring ipv6 windows vista it should easy. if have choosen prefix  fd43:b2bc:bc95::/64 (generated based on computers mac address see http://www.kame.net/~suz/gen-ula.html).

on server configured network this:

netsh interface ipv6 add address interface="local area connection" address=fd43:b2bc:bc95::1  netsh interface ipv6 set interface interface="local area connection" advertise=enabled  netsh interface ipv6 add route prefix=::/0 interface="local area connection" nexthop=:: publish=yes  netsh interface ipv6 add route interface="local area connection" prefix=fd43:b2bc:bc95::/64 publish=yes  

on test machine work pretty well. if try adapt configuration to our domain have problem router advertising remains disabled. tried on domain server (no other role installed) , on other server role installed "network policy , access services" routing , ras running.

if dump configuration following response:

> netsh interface ipv6 dump  # ----------------------------------  # ipv6 configuration  # ----------------------------------    pushd interface ipv6  reset  add route prefix=fd43:b2bc:bc95::/64 interface="local area connection" nexthop=:: publish=yes  add route prefix=::/0 interface="local area connection" nexthop=:: publish=yes  set interface interface="local area connection" forwarding=enabled advertise=enabled nud=enabled routerdiscovery=disabled managedaddress=disabled otherstateful=disabled advertisedefaultroute=enabled  add address interface="local area connection" address=fd43:b2bc:bc95::1  popd    # end of ipv6 configuration    ...     

however  the interface properties is showing following

interface local area connection parameters  ----------------------------------------------  ifluid    : ethernet_5  ifindex    : 11  state    : connected  metric    : 5  link mtu    : 1500 bytes  reachable time   : 26000 ms  base reachable time  : 30000 ms  retransmission interval  : 1000 ms  dad transmits   : 1  site prefix length   : 64  site id    : 1  forwarding    : enabled  advertising   : disabled  neighbor discovery   : enabled  neighbor unreachability detection : enabled  router discovery   : disabled  managed address configuration : disabled  other stateful configuration : disabled  weak host sends   : disabled  weak host receives   : disabled  use automatic metric  : enabled  ignore default routes  : disabled  advertised router lifetime  : 1800 seconds  advertise default route  : enabled  current hop limit   : 0  force arpnd wake patterns : disabled  directed mac wake patterns : disabled  

i tried figure out differences between test machine , designated advertisement server haven't found obvious differences. using procmon didn't either. netsh sets same registry setting on both machines. of course tried playing around other configuration options forwarding, router discovery , on. nothing helped. there must other system parameters prevents server adverting. know reason?

note: having default router advertised or not makes no difference.

btw: if asked question 2 years ago microsoft newsgroup nether got answer. hoped r2 fix there no difference between windows server 2008 , windows server 2008 r2.

any welcome

hi, found solution. turned out router discovery must enabled use advertising, try

set int "name" rou=e adv=e
