The same problem persists in 14.04. My DHCP server pushes two DNS servers: primary (10.0.0.3), located inside the local network and secondary (10.0.2.1), located in DMZ.
Primary server's zone includes records for some servers that are accessible only from local network.
Periodically (maybe after lease renew?) computer with 14.04 could not resolve local names which records are absent in seconary server's zone.
Workaround is to make internal view for secondary server's zone in order to let computers from local network resolve such local names.
