[Samba] Replication is broken due to Bind DNS resolution

[L. van Belle]

No, Samba Replication is not broken due to Bind DNS resolution. 
its broken because of a outdated and/or failty setup, but your close now to the fix.  

on all servers, run : 
samba-tool drs showrepl
and 
samba-tool dbcheck --cross-nc  
and fix it all. 

this server : > c0ad4d18-ce25-4198-8e21-694c0727fecf._msdcs.pukey. 900 IN CNAME kefka.pukey.  
its missing in sites and services, 

*  most probley due other servers being turned off, scaveing, don’t know, your thread is hard to follow
you need to readd it. 

So, I don’t know if you use the RSAT windows tools, goto "Active Directry Sites and Services"
Your missing a server there, re-add it, I don’t know the CLI for that, never used it. 

Then as last, find the best "working server, and then push that database to the other DC's. 
reboot the other server ( not the best working ) and check replication again. 

I hope this helps a bit. 

Greetz, 

Louis
