Re: [Samba] Samba AD DC replication error - 2, 'WERR_BADFILE'




Thanks for the fast reply.
Sorry - I was not aware that attachments are not forwarded.
(All information you requested was included there)

I think I have already tried resync via "samba-tool drs replicate" - but
better see below the printout of previous attachment "faiserver.log"

Thanks for help in advance :)
