Looks like:
https://bugzilla.samba.org/show_bug.cgi?id=9500
>From the source code:
WERR_DS_DIFFERENT_REPL_EPOCHS =
The directory service cannot perform the requested operation because the servers involved
are of different replication epochs (which is usually related to a domain rename that is in progress
So yes, you did hit a nice bug, this is one why i never ever ever ever change domainnames/servers after the domain is setup.
How to fix this, i really dont know. (sorry)
