On the original AD DC I see this error:
/usr/sbin/rndc: Failed to exec child - No such file or directory
[2020/06/25 15:38:50.565496, 0]
../../source4/dsdb/dns/dns_update.c:91(dnsupdate_rndc_done)
../../source4/dsdb/dns/dns_update.c:90: Failed rndc update -
NT_STATUS_UNSUCCESSFUL
But there is no rndc program anywhere on this system. And internal DNS is all
that was ever enabled.

Why is samba trying to run rndc?
