Don't know - never used sites in a-Windows-only AD.

Sorry, I should have been more explicit, I deleted the entries under the child (_tcp) eg the _gc, _kerberos & _ldap SRV entries,
then tried to delete the _tcp child entry to work up the tree.   However, since I posted the first message in this thread, I ran
"samba-tool dbcheck --cross-ncs --fix" and it found (and fixed) deleted entries.    I have checked DNS Manager again and the branch
has been removed from the <dns-domain> zone.   The other zones, eg DomainDNSZone and the ForestDNSZone (where I didn't delete the
SRV entries) the <site-name> branches are still present.   I assume therefore if I delete all these SRV entries it will get sorted.
But shouldn't they get removed automatically?   (Clearly the other site was deleted automatically, but maybe that's because I
demoted the DC that was in that site?   Whereas I just moved the DC that was in this site back to Default-First-Site-Name.)
