Greetings, Sam!

> Hello all,

> I'm always trying to migrate from W2000 server to Samba 4.

> - install a Sernet Samba4 with Bind9, join W2003, transfer roles -> done

> At this point the sync process is working in two way, I can manage DNS

> But now Samba4 always trying to contact the w2003 server and I can't

> Thanks for helping! :)

Did you transfer all seven roles?
