[Samba] samba 4 joining a Windows 2003 srv / Sync and DNS problems

[Sam]

hello,

After a lot of different approach to move from an old windows 2000 
server AD to samba4, my last try seems nearly good now...
I did this :
- Preparing the old DC with adprep commands
- add DNS and AD roles in a new temporary win 2003srv
- add this new server as an AD controller
- transfer all roles to win2003 with ntdsutil command
- demote win2000
- put the AD domain and forest functional level to 2003
- move _msdcs in the DNS management tool as described here 
(http://support.microsoft.com/kb/817470/en-us)
- adjust all zones with "Nonsecure and secure" Dynamic updates
- adjust all zones with Replication "To all DNS servers in the active 
directory forest ariane.intra"
- join a new sernet samba4 server.


A lot of things works, I can use rsat tools for managing the dns and the 
AD users of Samba4.
But some things disturbing me...
Replication works only in one way

during Samba4 join I had see that :

descriptor_sd_propagation_recursive: 
DC=DomainDnsZones,DC=ariane,DC=intra not found under DC=ariane,DC=intra
descriptor_sd_propagation_recursive: 
DC=ForestDnsZones,DC=ariane,DC=intra not found under DC=ariane,DC=intra

and now if I do a "samba-tool drs showrepl" command, I thinks it 
missings these parts ( DomainDnsZones and ForestDnsZones)  in OUTBOUND 
sections  :

What can I do on the win2003 Ad to fix this?

Thanks all!
