> Back to newly joined DC I launched samba_dnsupdate, on 10 DC this command

>> Hai Louis,
>>
>> I should be able to answer you tomorrow: I pushed installation of 10 DC
>> before leaving work and this process would not be able to use workaround
>> described earlier because of SSH not yet open between the two sites. I
>> expect all other needed ports to be open, so I expect only the replication
>> workaround to be failed this night.
>> So tomorrow I should arrive at work with 10 DC joined to my AD and just
>> rebooted.
>> FSMO would not have been rebooted at that moment. If no replication took
>> place in the night I'll try to reboot FSMO then to reboot all DC one by one.

>>> I must ask..
>>> Did you reboot the servers after you added the second server to the DNS?
>>> And especialy in order, DC_with_FSMO, wait until its up again, then DC2.
>>> This often fixes the repliction problem and as far as i know, this only
>>> happend just after the install of a extra DC.
