Reverse DNS trauma

Hi,

Any ideas why my BIND server is not authoritive for a zone it has a zone
file for?

Let me explain... I've currently got reverse DNS managed by a Microsoft DNS
server, but I want to move everything to BIND 9 on linux.  The forward
lookups work exactly as I'd expect, and I thought I'd set everything up
right. Feeding the reverse zone files I wrote into MS DNS works, but when I
try and query the BIND server using the same zone files this happens:
--------------------------------
% nslookup -sil
> set type=ptr
> set norecurse
> 195.224.199.40
Server:         195.224.180.227
Address:        195.224.180.227#53

Authoritative answers can be found from:
199.224.195.in-addr.arpa        nameserver = kamet.pncl.co.uk.
--------------------------------


Surely if the zone is being hosted by this server the answer should be
authoritive?  With recursive queries turned on, it works, but that's because
it's querying the NT box.


-------------------------
Here are the first few lines of my reverse zone file:
-------------------------
$TTL 88400
@       IN      SOA     solo.pncl.co.uk. root.solo.pncl.co.uk. (
                                2001061800      ; Serial
                                10800           ; Refresh
                                3600            ; Retry
                                604800          ; Expire
                                86400)          ; TTL

          IN NS   solo.pncl.co.uk.
40      IN PTR  gecko.pncl.co.uk.

-------------------------
and here are important lines of the named.conf file:
-------------------------

zone "199.224.195.in.addr.arpa" in {
        type master;
        file "199.224.195.in.addr.arpa";
        allow-transfer {...stuff;};
        also-notify {...stuff;};
};

Thanks,

Tim
