Situation
IF the OES DNS server is authoritative for a domain
AND it is also authoritative for a subdomain that was created as a Forward zone
THEN name resolve for anything in the subdomain results in an NXDOMAIN error.
The OES DNS server does not attempt a forward for any queries in that subdomain.
If the subdomain is instead for a different domain that this DNS server is not authoritative for then forwarding occurs as expected.

Example Config: DNS1 mycomp.zone - Primary lab.mycomp.zone - Forward to DNS2 test.other.zone - Forward to DNS2 DNS2 lab.mycomp.zone - Primary test.other.zone - Primary Test Pointing at DNS1 all records resolve in mycomp.zone Pointing at DNS1 no records resolve in lab.mycomp.zone - Looking at a LAN trace there are no attempts to forward to DNS2 at all. - tcpdump -any -s0 host dns2 and port 53 Pointing at DNS1 all records resolve in lab.other.zone because this one does forward as can be seen in the same LAN trace output.
Resolution
Create the subdomain as a Secondary zone rather than a Forward
zone.
