We have several NetWare 5.1 DNS/ DHCP servers. They all handle our main
domain. This works without issue.
If they cannot resolve a domain name they forward to two DNS / DHCP
servers that are setup to forward to our ISP. This also seems to work.
We also have quite a few secondary zones. These are serviced by the same
servers setup to do the forward look. I have noticed that if a remote PC
does a lookup on a device in the secondaries their DNS returns no IP
address. The remote PC uses their local DNS that I think should do a
forward to the other two and get an answer.

Any clue what is setup wrong?
