 From the official Samba wiki! :-)

https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory

"Running one domain controller (DC) is sufficient for a working Active Directory (AD) forest. However, for failover and load balancing reasons, you should add further DCs to your AD forest."

#facepalm


> As far as I am aware, all DC's are equal except for the FSMO roles and these can be on any DC. So terms like 'pdc', 'backup' and 'failover' are meaningless, they are all just a 'DC'.

Can someone change or add that to the Samba wiki then please?

I was very careful NOT to use the word secondary because we've had this dicussion before.

I just want (what's the phrase?) "another" DC in the network for this very situation where "one" DC with the FSMO role does not work and have replication.

I've obviously done something wrong, and I am keen to learn and fix it.

Nope.

I have both DCs as DNS and the "other" DNS server (dc4) was available and working at the time.

Thanks.
