Help on: BIND 8.x and 4.x For Solaris, all Solaris 2.7 or greater operating systems come pre-built with DNS BIND 8.x. Before Solaris 2.7, Solaris machines came pre-built with BIND 4.x. In some cases it may not be clear what version of BIND you are running. If this is the case, you may select the choice button: "BIND 8.x and 4.x" to force DNS Boss to write to both: /etc/named.boot (BIND 4.x), and /etc/named.conf (BIND 8.x). This should allow your DNS server to serve DNS requests no matter what version of BIND your machine is running. If you build a custom version of BIND, and do not build it into: /usr/sbin/in.named, then you must go to the Advance menu and select: 'Set the path to the named executable'.
