[Samba] "failed to lookup DC info for domain over rpc" when joining samba4 domain
Hi, I have an existing samba4 domain with 2 domain controllers on different sites. Both domain controllers are running samba 4.1.17 Until recently the domain operated exactly as expected. I recently tried to join a new machine to the domain and received the error: Failed to join domain: failed to lookup DC info for domain 'ADS.CONNON.ME.UK' over rpc I'm not sure what has triggered this change in behaviour. Authentication against the domain still works as normal. I've attached a full debug log of the domain join process. Anyone got any ideas where I should be looking? Regards, Richard

Hi again, Seems you can't attach items to mails on this list so here's the debug log: http://www.irconan.co.uk/net-ads-join.log Regards, Richard On 09/03/2015 21:33, Richard Connon wrote:> Hi, > > I have an existing samba4 domain with 2 domain controllers on different > sites. > > Both domain controllers are running samba 4.1.17 > > Until recently the domain operated exactly as expected.

Hey Richard, you should post your debug log because your attachment has been scrubbed. Have you checked your DNS entries? I don't know why but I had an issue some days ago that the host a entry for my fsmo DC had disappeared. Regards Tim Am 9.

I think I know, but it would like you to confirm my suspicions. Rowland

Hi Tim, I re-posted with a link to the debug log. I appear to have A and AAAA records present for both DCs. Not sure about the relevant SRV records used in domain join. Got any pointers on how they should look?
