Hi Marc


Samba 3 smb.conf
  workgroup = ABC.ORG.ZA
  netbios name = ABCSERVER

Samba 4 smb.conf
        workgroup = ABC
        realm = ABC.ORG.ZA
        netbios name = ABCSERVER

samba-tool domain classicupgrade --dbdir=/root/samba3/private/ --use-xattrs=yes --realm=ABC.ORG.ZA --dns-backend=SAMBA_INTERNAL /root/samba3/smb.conf -d 3

I had many duplicate SID which took a very long time to sort out but all working now. PC's without duplicate SID didn't need to rejoin the domain either.

I'm not sure, if I understand your problem. Do you mean that your NT4
NetBIOS name contains the dots (bad!)? And after running the classic
upgrade you're having problems with that?
