Hai MJ, ( gelukkig nieuwjaar he .. ;-) )
First, why sernet 4.2.5 current is 4.2.7 Upgrade to 4.2.7 first i suggest.
And : Last attempt @ Wed Nov 11 <= 11 Nov ? latest really?
The "misbehaving server" check the time first.
Try to run :
knit Administrator
samba-tool drs replicate <destinationDC> <sourceDC> --full-sync -k
reboot your server, check time, check logs.
Ow and for you to know. You mail A/MX are wrong for list.
<lists at merit.unu.edu>: host postoffice.merit.unu.edu[2001:610:1208:6:192:87:143:1] said: 550 No RDNS
entry for 2002:c386:ad78::1 (in reply to RCPT TO command)
2002:c386:ad78::1 should resolve back to ipv4. My server does not have a "real ipv6" number
Greetz,
Louis
