I did this to my server, and it doesn't make a difference. I have posted about it in the last few weeks, but nobody seems to come up with any answers. I finally sent it in as a bug, but have yet to hear anything from that as well.
Have a LAN with a name subnet of 1.2.3.x with a name of "mynet.edu". DNS server is 1.2.3.1 and is primary for "mynet.edu". If I go to any workstation, I can ping printer.mynet.edu without any problem because it is in the primary DNS table. Go to my stand-alone SME v5.x box (sme.mynet.edu), do a ping to printer.mynet.edu, it doesn't know it. Why? The SME box thinks it is primary for "mynet.edu". If I go into /home/dns/etc/named.conf and comment out the arpa and zone for this subnet, all is well. But why should I have to do that, I already told SME the primary DNS for my LAN was 1.2.3.1.
