samba - Feb 2015 - Failed DNS update - NT_STATUS_IO_TIMEOUT ( and solved)

Hai, 
?
Just a tip for the people reading the list. 
?
if you see Failed DNS update - NT_STATUS_IO_TIMEOUT? or messages : ?RPC
unavailable if you connect from windows client to the samba AD DC server
?
Read this.
?
I have a "test' AD DC on a XEN server running and this DC does nothing.
1 pc ( win7) is joined, some dns recored are set, nothing special.. 
?
today i checked the logs, and totaly out of the blue is see..? 
?
?
[2015/02/24 15:11:44.480393,? 0] ../source4/smbd/server.c:370(binary_smbd_main)

? ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - NT_STATUS_IO_TIMEOUT
.... until today.. 
?
?
now i did see.. 
samba version 4.1.16-SerNet-Debian-9.wheezy started.

and i just remembered i saw and upgrade to 4.1.17.. 
?
apt-cache policy sernet-samba-ad
sernet-samba-ad:
? Installed: 99:4.1.17-9
? Candidate: 99:4.1.17-9

so correct.. 
?
( for debian apt-get install debian-goodies ) 
i checked with : checkrestart 
?
and checkrestart reported me to?restart: 
service sernet-samba-ad restart
service ssh restart
service sudo restart
service sernet-samba-smbd restart
service sernet-samba-nmbd restart
service bind9 restart

restarted, checked again, again the same restart?where adviced. 
so i restarted the server, and here you go... 
away are the 
?
Failed DNS update - NT_STATUS_IO_TIMEOUT messages. 
?
?
Point of this story.. 
?
if you have : RPC Errors, or Failed DNS update - NT_STATUS_IO_TIMEOUT 
check the running version and the installed version and restart samba
services?or your server.
?
?

Your saying you had to restart twice to get "checkrestart" to clear
up?
