Hello Rowland, thanks for your help.

My replies lines below:

Yes, they both point to each other just as you suggested.

I've just configured NTP on both servers, they now have only 1 seconds
of difference.

What type of DCs are these two servers? Some kind of two Primary or
Master DC each one? Shouldn't I have a PDC and a BDC? (I thought this
the recommeded setup for DCs). Please let me know if I'm doing
anything wrong here.

I'm going to check if samba_dnsupdate error messages dissapear in the
following minutes/hours after synchronizing both servers using NTP,
but I don't know what caused this error. Was it really caused by time
differences between servers? or is there anything else that might need
to be fixed?

Thanks again
