Hello, i posted to the list previously about some dns anomalies and keep running into some warnings and errors. 8015 (cat 1028) Failed to register host resource records (A or AAAA) for network adapter with the following settings: Adapter name: {1DEF68B5-96DA-4671-865E-901375F5F0E7} Hostname: HOSTNAME Primary domain suffix: my.domain DNS server list: 192.168.50.1, 192.168.50.11 Server the update was sent to: 192.168.50.1:53 IP address(es) : 192.168.50.163 These resource records could not be registered because the update request sent to the DNS server timed out. Most likely, the DNS server authoritative for the registration or update is not running. You can manually perform DNS registration of the network adapter and its settings by typing "ipconfig /registerdns" at the command prompt. Contact the DNS server or network system administrator if the problem persists. Also some 1014s about DNS timeout on both Servers DC01 Netplan network: version: 2 renderer: networkd ethernets: eno1: addresses: - 192.168.50.11/24 nameservers: search: [my.domain] addresses: [192.168.50.11, 10.0.1.9, 192.168.50.1] routes: - to: default via: 192.168.50.1 Resolvconf search my.domain nameserver 192.168.50.11 Smb.conf [global] min protocol = NT1 dns forwarder = 1.1.1.1 netbios name = DC01 realm = my.domain server role = active directory domain controller workgroup = my idmap_ldb:use rfc2307 = yes log file = /var/log/samba/%m log level = 3 template shell = /bin/bash winbind use default domain = true winbind offline logon = false winbind nss info = rfc2307 winbind enum users = yes winbind enum groups = yes [sysvol] path = /var/lib/samba/sysvol read only = No [netlogon] path = /var/lib/samba/sysvol/my.domain/scripts read only = No DC02 Netplan network: version: 2 renderer: networkd ethernets: eno1: addresses: - 10.0.1.9/24 nameservers: search: [my.domain] addresses: [192.168.50.11] routes: - to: default via: 10.0.1.253 Resolvconf search my.domain nameserver 192.168.50.11 Smb.conf [global] min protocol = NT1 dns forwarder = 1.1.1.1 netbios name = DC02 realm = my.domain server role = active directory domain controller workgroup = my idmap_ldb:use rfc2307 = yes [sysvol] path = /var/lib/samba/sysvol read only = No [netlogon] path = /var/lib/samba/sysvol/my.domain/scripts read only = No Do you see what is wrong?
