Apparently I missed a step somewhere! On DC01 /etc/systemd/resolved.conf says [Resolve] #DNS= #FallbackDNS= #Domains= #LLMNR=no #MulticastDNS=no #DNSSEC=no #DNSOverTLS=no #Cache=yes #DNSStubListener=yes #ReadEtcHosts=yes On DC02 it reads [Resolve] DNS=8.8.8.8 FallbackDNS=8.8.4.4 #Domains= #LLMNR=no #MulticastDNS=no DNSSEC=no #DNSOverTLS=no #Cache=yes #DNSStubListener=yes #ReadEtcHosts=yes So the DNS line should be the IP of the DC it's on, correct? FallbackDNS? should that be 8.8.8.8 or...

...in the base  /etc/hostname, /etc/nsswitch.conf and /etc/resolv.conf or systemd  cointains wrong settings, you might inherit these. So it might be that a previous samba was accepting these settings, but a latest samba not. Or a previous systemd version accepted these and a newer not..   Setting : DNSStubListener=No in /etc/systemd/resolved.conf. is correct also, yes, its what you preffer, i mask the needed services.   >hostname is DC1, confirmed by hostnamectl, resolv.conf has just two entries: nameserver (own IP), and search samdom.example.com. Same as it is now, so this all works. Just that because...

Thank you everyone for your help. I corrected my resolv.conf files as Peter Milesson suggested and then had to take a number of extra steps so now things are looking a little better. In case it helps anyone else in the future, here's what I found (plus I am now having problems resolving internal addresses). As far as I can see, the setup on both servers is identical (except they use their own
