Our DNS/DHCP server (10.2.0.6) is Netware 6.5 sp 5a. We currently have only
local IPs (10.2.0.0 subnet) in our DNS.
Using DHCP we set our workstations to use 10.2.0.6 as the primary DNS, and
139.142.2.2 as the secondary DNS.

The problem was that if we set the primary DNS as 10.2.0.6, some of our
WinXP sp2 workstations will fail to use the second DNS (and fail to resolve
external IPs) . If we reverse the order, and use 139.142.2.2 as our primary
DNS server, some of the workstations will fail to find internal IPs (since
10.2.0.6 is our secondary DNS).

So we tried using DNS/DHCP management utility to set a single DHCP DNS of
10.2.0.6 and a "Forwarding List" entry of 139.142.2.2 (restarted the
server). It still failed to resolve external addresses (so I assume it
failed to forward unresolved queries to 139.142.2.2).

Obviously I'm doing something wrong with the forwarding. Any suggestions?
Thanks.
