We managed to get DNS setup using BIND9 on our Raspberry Pi data center. We go over what we did, how we did it, and what we learned. This was a little tricky because BIND has several config files. We also had to reconfigure the DHCP server so Dorothy's workstation would get the correct DNS servers. 

See our master BIND9 configuration files on our website. We've included named.conf.local and the forward and reverse lookup config files.
