Hello you all, I have a general question. How do you guys handle the PTR record in AD if the workstations update their own records? The A record is no problem as this contains the name and is onyl updated by the corresponding machine. However, the PTR record could be tried to update by a different machine if that IP has been passed to a different machine by DHCP. With windows AD with scavenging of the records this probably is a small problem. How do you handle this?

Hi Christian, normally I never do a reverse lookup for clients only for server and then the reverse lookup is static. If a customer want's it I do it this way: https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_BIND9 Stefan Am 03.07.19 um 11:41 schrieb Christian Naumer via samba:> Hello you all, > I have a general question.

However, this leaves out the VPN users as they get their IP from the firewall not the DHCP-server. And it also has a problem with laptops which have two interfaces (wireless and wired). The interface that comes up last overwrites the already existing entry (even if windows does not use the wireless interface later and uses the wired with the higher priority). Those are the reasons we wanted to switch. Regards> > Stefan > > Am 03.07.19 um 11:41 schrieb Christian Naumer via samba: >> Hello you all, >> I have a general question.
