Ok we need much more information

You have to locate the DN for the DNS zone, first to  this seach:
ldbsearch -H ldap://<ip> --cross-ncs '(cn=partitions)' dn
Then
ldbsearch -H ldap://<ip> -b <dn>
Where <dn> is the DN you obtained from the first search
You will find 6 objects normally it's the different naming context, 
locate the 2 ones relates to dns.
Do the following

ldbsearch -H ldap://<ip> -b <forestzonedn> repsfrom repsto --show-binary
ldbsearch -H ldap://<ip> -b <domainzonedn> repsfrom repsto --show-binary

Send us the result
Also can you post the result of samba-tool drs showrepl

Can you also use repadmin on the windows 2008R2 server to get info on 
the replication (according to windows 2008R2).

Also in order to get a better view can you use wireshark to monitor the 
traffic between the 2 DCs, and the on Samba create a new DNS record (ie. 
samba-tool dns add dcname zonename foo A 1.2.3.4), in the wireshark 
trace you should see a couple of drsuapi calls and more exactly 1 
dsreplicasync emitted from Samba (this is a replication message to tell 
the other DC that there is something to fetch) and the getncchanges from 
the Windows DC to actually get the changes.
