Hi, SRV records have been working fine until my hoster decided to upgrade BIND. working wrong syntax: _sip._udp SRV 10 10 5050 mydyndns. correct syntax: _sip._udp IN SRV 10 10 5050 mydyndns. That kicked of one of my domains completly caused by a syntax error that did no harm to the previous version After inserting the missing "IN" the zonefile loaded but now I can't query for the SRV record: jo@lancelot:~> host -t SRV _sip._udp.mydomain Host _sip._udp.mydomain not found: 3(NXDOMAIN) Any suggestions, jo
