Hello people,

I don't understand what this means.
I have a NT4 PDC and a NT4 BDC : they are on a different network.
The BDC is old and i'd like to upgrade to Samba3.

Do you think it is possible or not ??

What it means is that if you want Samba to be a BDC, then the PDC has
to be Samba also.  So, no, it is not possible, as long as your PDC
remains NT4.

As I understand it, both primary and backup domain controllers, must be
either Windows or Linux.  You can't mix them
