DHCPv6 client in Windows 10 broken after anniversary update

So I did some more investigation. I had missed that I needed to use
/renew6 and /release6 before.
Now I have 10 minute lease time.
5 minutes into the lease time, I can /renew6 the lease successfully and
get 10 more minutes leasetime.
around 2-3 minutes before the lease-time expires I see that Win10 has
marked the IA_NA as (deprecated), I try to do "/renew6" I get the
"An error has occured while renewing interface Ethernet: The semaphore
timeout period has expired".
This renew fails. If I now ctrl-c this /renew6 and run /renew6 again, the
renew succeeds and the address is back again as (preferred) and the lease
time is 10 minutes.
I also have a Ubuntu 16.04 box that won't keep its lease either... so I
don't know what's going on. Will look further.
Harald, what DHCPv6 server are you using?
