I installed
two virtual machines with Samba as domain controllers for the same domain. I
was struggling with network and DNS configuration initially, maybe my problem
is related. 

DC1 starts
up ok, the last line of the log reads

'samba' finished starting up and ready to serve connections

DC2 starts
with plenty of lines

  ../source4/dsdb/dns/dns_update.c:294: Failed
DNS update - NT_STATUS_UNSUCCESSFULBoth use bridge network configuration, static IP addresses, /etc/resolv.conf points to themselves (and the other), they can ping each other, but DC1 cannot resolve the name of DC2. I was assuming that the name information is part of the replicated information?When DC2 joined
DC1, resolv.conf was pointing to DC1. I changed that later on as I want to be
able to continue to operate DC2 while DC1 is down. Ultimately I want to run the
DCs in two different networks that may occasionally become disconnected.

What am I doing

Thx -
