I have a W2K sp4 server with DNS
server installed. All Ok until 2 day ago,
now when I open DNS manager I don't see
my direct zone and the reverse zone !!
If I try to recreate the zones the system tell my
that "The zone already existing".
In the \winnt\system32\dns directory
i find my right dns files (mydomain.com.dns
and 0.4.192.in-addr.arpa.dns files).

I have try to re-register the dns server with ipconfig
but nothing happens.

If I try to interrogate the DNS server with nslookup
I have this message:"Impossibile to find name server for
192.4.0.100 IP: Non-existent domain"

Any suggestions?

thank.

DNS servers pretty much NEVER do that -- someone
deleted them or your report is likely in error (see below...)

How specifically? Is the server on the same machine with
the Management Console? Is the server showing there?
Is the server STARTED (running)?

Net start "Dns Server"
(might help if server isn't running -- and then refresh console)

Of course, this has NOTHING to do with the operation of the
DNS server.

This command causes the CLIENT (even if on the same machine
as the DNS server) to re-register it's NIC IP address and name
with DNS (it is also insufficient for re-registering a DC.)

I have this message:"Impossibile to find name server for

That is normal -- it is a FAQ that NSLookup reports this
spurious error for any DNS server IT USES that has no
REVERSE zone PTR record -- IGNORE this.

Does it give the ACTUAL answer down below the error
or does it time-out? (If it times-out then it probably isn't
running -- see above.)

yes the server is already start !

yes I use Manager Console on DNS server
Is the server showing there?

yes my dnsserver is showing

yes I know,but I try to check if the dns server is up
and ready to answer to a question!

If I check on AD users and computer on MicrosoftDNS
object I find my zone !
I try to delete the "mydomain.com.dns" file and try to
recreate it but I have allways the same errore the "zone
already exist"

Any suggestions?

Well, ipconfig /registerdns won't give you that kind of feedback
either.

Use NSLookup (or a substitute) or just use Ping. Problem with
ping is you cannot specify a DNS server to query and once it works,
you have it in cache.

Nslookup allows the server to be specified and it bypasses cache.

Pretty much irrelevant to ever do that. If you create the zone
as "AD Integrated" then it will populate from those AD records
but otherwise they are pretty useless.

That's a file name (probably) -- What is you domain name
EXACTLY?

Do you have at least two tags, domain.com, but not just DOMAIN.
Does the machine (system control panel) have a full domain name,
machine name + domain name?
