I'm trying to use the DnsModifyRecordsInSet API to add (and update) A
records in a Windows 2000 DNS Server. So far, all I can get out of it
is an error return (9002: DNS_ERROR_RCODE_SERVER_FAILURE). I have seen
many other postings asking this same question, but no resolution.

I tried building the sample in the SDK
(Samples\netds\DNS\ModifyRecords), but it returns the same error. Just
to simplify things, I'm running this on the DNS server machine itself,
logged in as Administrator.

If I add the record manually, I can query it just fine (did this using
the other sample, DNSQuery). I also installed dnscmd; it does seem to
be able to add records.

I installed Ethereal so see what the network traffic was; all I see is a
query for the SOA, and the response. I enabled all logging in the DNS
Server, and it shows the same thing (log is below).

I've been through the DNS server configuration, and it all seems OK. I
have enabled DNS Updates. This DNS server is not active directory
integrated (it's a standard primary zone). I am at a complete loss as
to what to try next; any suggestions?

TIA,

--mkj
