simple local caching DNS

I'm setting up a local caching DNS server on a Windows network
using the example files from www.madboa.com/geek/soho-bind
They are similar to, but a bit more complex than the caching example
in the bind documentation. I have setup other DNS servers that actually
serve multiple domains, but this is my first one that is CACHING ONLY.
It IS working. I can enter it as the ONLY DNS server in the network
properties of the Windows workstations, and they can still resolve
names using nslookup and web surfing, but the problem is when I
add secondary name servers, and test with nslookup.
In this case, with my new local caching DNS as primary and the ISP's
DNS as secondary (in case mine goes down) when I try to verify
using nslookup at the windows workstations, they come back with
and error that they can't find the name of my local DNS then proceed
to use the secondary DNS from the ISP. Here is the nslookup output:
*** Can't find server name for address 10.15.10.2: Non-existent domain
Default Server: ns1.sprintlink.net
So it looks like the resolver function on the windows workstation is NOT
using the primary DNS because it can't find a name for it. But I'm not
sure about adding the its name to a zone file, because the company's
domain and name servers are hosted offsite, and I don't think I want to
put the internal address of a name server on out there.
Should I just make a reverse zone for that machine?
