Joe,
What are you typing to query for the record?

Allen,
I can see the record in DNS manager, and in the .dns file. I've tried
querying for the PTR record both in command line nslookup and via
dnstools.com. Both approaches result in no records returned.

Thanks,
Joe

How are you doing the query?
Can you see the PTR record using DNS admin tools?

Alan,
Thanks for the reply. I tried your more direct approach with no luck.
Please note that I masked my real IP address range for purposes of
posting.
The real address is a subnetted class C. I've been approaching this
problem
as if I had reverse DNS delegation authority (which I do not for this
particular subnet.) But I'm not doing a rDNS query, simply querying
for a
PTR record. So I'm confused as to where the problem lies. Is it in
the
zone
file, the reverse delegation authority, or something else.

Thanks,
Joe

You've misunderstood how the zone files are created and what namespace
they're authoritative for.

Your zone needs to be 100.168.192.in-addr.arpa. Its not aware of the
network
mask you're using and will become authoritative for the whole
192.168.100
range.

Once you've created it you'll need some records in it. Make sure
you've
got
one or more PTR record either created or dynamicaly registered with it
and
ensure you can perform a lookup using NSLOOKUP <IP ADDRESS>. Once
you're
sure its working go for the replication and re-check against the
secondary
server.

Good luck.

I have a Win2K DNS server as my authoritative DNS server. I am
trying
to
setup a reverse lookup zone for a classless IP range that responds
to
outside
queries. I have setup a zone using the following information:
subnet = 28
subnet mask = 29
IP address 192.168.100.225

So my new zone looks like this:
28-29.100.168.192.in-addr.arpa

I then add the appropriate PTR record to the zone and replicate it
to
my
secondary DNS server.

The problem is that when I do a query for a PTR record for the host
'server.domain.com', I get the response that no PTR record exists.
The
response is coming from the correct name server. I have no idea
what
the
problem is. I've tried variations in the zone name
(28_29.100.168.192)
with
no luck.

Can anyone tell me what I'm dong wrong?
Thanks,
Joe
