Hi, I build a setup on a Debian Wheezy with samba 4.0.9 and a compiled bind 9.8.4 with this configure options: ./configure --prefix=/usr \ --mandir=\$${prefix}/share/man \ --infodir=\$${prefix}/share/info \ --sysconfdir=/etc/bind \ --localstatedir=/var \ --enable-threads \ --enable-largefile \ --with-libtool \ --enable-shared \ --enable-static \ --with-openssl=/usr \ --with-gssapi=/usr \ --with-gnu-ld \ --with-geoip=/usr \ --enable-ipv6 \ --disable-linux-caps \ --disable-threads \ --with-dlopen=yes After that I added a host with the Windows Management Konsole and changed the IP. But when I dig after it, I saw that both addresses are served: root at sambas9:~# dig @localhost kerios9.domain.local ; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> @localhost kerios9.domain.local ; (2 servers found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 17655 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;kerios9.domain.local.
