I get a feeling this is going to be less of a bind issue, and more so some other configuration issue(s).

Have you validated the DNS server IPs that are assigned to the clients have the correct IP(s) set for the bind server? Is the browser using the OS settings for dns, or are they trying to do DNS over https directly out to the Internet to other dns servers? Are you sure there is only 1 dhcp service active on the network? Is the WAP doing dhcp as well and giving conflicting options maybe? May 9, 2025 6:58:47 PM bi...@clearviz.biz: > Howdy all!.
