Thanks Rowland and Louis! :) Ok I'm going to test the failover mode! ;) Do I need to set the same value for NSRVS in dhcp-dyndns.sh? ( the first AD server, "S4" for me ) Or can I keep NSRVS=S4.ariane.intra on server S4 and NSRVS=S4bis.ariane.intra on server S4bis? It seems to be more secure for me if the first server switch off...

...P failover, can you tell me how to do to to have manually dhcp start method working... I think I could made a mistake, this is what i did : ( I using Louis script from "old set of script" directory : https://secure.bazuin.nl/scripts/ ) - On server S4 : resolv.conf set to S4 first and S4bis in second - On server S4 : in dhcp-dyndns-debian.sh, NSRVS=*S4*.ariane.intra - On server S4 : bash install.sh - On server S4 : osync set to sync dhcpd.conf between the 2 servers - On server S4bis : resolv.conf set to S4bis first and S4 in second - On server S4bis : in dhcp-dyndns-debian.sh, NSRVS=*...

Hello All, I have 2 samba4 AD server with dhpd and dynamic DNS. I have well understand that for now it's not possible to have 2 DHCP server running in the same time. So I would have at a time only one dhcp server running. If the first server got a problem I want to manually start the isc-dhcp service in the second to rescue the system. But It's not working as I expected... If I switch
