In MS W2k DNS there are four options for controlling zone transfers.
These options are per zone; there is no global zone transfer option.

1) No zone transfers
2) Allow zone transfers to anyone.
3) Allow zone transfers to the name servers in the NS table.
4) Allow zone transfers to specific IP addresses.

I use 3) instead of 4) because I have six BIND slaves with a total of
ten IP addresses. And I did not want to enter each of the 10 IP
addresses for each of the 92 zones on my W2k+3 DNS Server. As I have
mentioned in previous postings, for a zone transfer to be allowed, the
mapping

IP-address IN PTR nodename

must be in the W2k DNS cache for the zone transfer to be allowed. If
the PTR record is not in the cache, the MS code will NOT do a DNS query
to locate the information, as that information may come from a
hijacked DNS server. When I have this situation, I run the following
command

nslookup IP-address w2k-dns-server

This will ask the W2k DNS Server for the PTR record, and if it does
not have it in its cache, it will retrieve the record from DNS,
just as the DNS protocol states.
