- Laptop (M1 Pro, macOS 15.3.2) is connected to a dual stack network via Wi-Fi with home.arpa as the search domain.
- DNS resolver forwards requests for home.arpa to a local authoritative DNS server (CoreDNS).
- CoreDNS zone file includes SOA, NS, AAAA, A, PTR, SRV, and TXT records for services like SMB.
- dig commands confirm DNS records resolve correctly (PTR, SRV, A, AAAA).
- dns-sd commands show browsing for _smb._tcp.home.arpa but no services are discovered.
- Finder->Network shows home.arpa but it's empty, indicating service discovery issues.
- DNS server logs show SOA queries for various services (_afpovertcp, _smb, _rfb, _adisk, _tcp), some returning NXDOMAIN.
- Debugging needed to identify why service discovery fails despite correct DNS resolution.
