DNS Problems


G

Guest

Hello all,

I have just taken over a network with the following issues:

1. DNS W2K reading event ID: 3000

2. Doing an NSLOOKUP IP-ADDRESS gives me the name of a server
"wrong-server-name" neither in use nor on my network! Doing the NSLOOKUP from
the DNS server CMD prompt gives me the same answer.

I go into the DNS console and the entry is in for "correct-IP-address" =
"correct-server-name" is in as a record, but the NSLOOKUP tells me something
different. I have also issued the IPCONFIG /FLUSHDNS for the boxes with no
joy.

3. I have now been told not to reboot my DNS box by my old counterpart (he
now works elsewhere). Because the DNS records will revert back to January
07??

We have trusts to other domains/companies and the DNS is quite extensive so
I'm loathed to reload/clear cache the DNS incase it all goes wrong!

Future plans will: Built a secondary DNS server.

However for the now, how can I fix the above problem, I have a felling all
my symptoms are tied together somehow, I just don't know where?

Thanks.

You can flush the DNS Client cache all day long and it won't change the
output nslookup gives you because nslookup bypasses the DNS Client cache.

Oh really? I would like to see that one.

I agree with Kevin that the last point you stated is an odd issue. Can you
post an unedited ipconfig /all of this server please. That will give us a
better starting point in additon to the other info asked to be posted.

THanks,

Guys I will get back to this issue as soon as I can, but I'm fire fighting
other issues at the moment.

I will post the results as requested soon.

1. Check in the reverse lookup zone.. running nslookup <IPAddress> only causes
nslookup to perform a reverse lookup on the IP Address.


2. You can flush the DNS Client cache all day long and it won't change the
output nslookup gives you because nslookup bypasses the DNS Client cache.


3. I have now been told not to reboot my DNS box by my old
counterpart (he now works elsewhere). Because the DNS records will
revert back to January 07??

Oh really? I would like to see that one.

***********************************

1. In the reverse lookup zone I found the old offending entries, this is now
fixed.

2. I did flush the DNS all day long, but my fingers got sore from hitting
the buttons ;-) (thanks for that I did not know).

3. Well I wouldnt like to see that one!

Yes, I saw that. Thanks.

How about an unedited ipconfig /all please? That will better help us to help

Does:
Primary DNS Suffix . . . . . . . : Domain-Name (good)
match the actual AD DNS domain name?

As far as reverting back to January 07, that doesn't make sense at all. Do
you mean the time stamp on the RR (host records) are reverting back to Jan
07? Are you looking in DNS while in Advanced view? Based on the ipconfig
above, it looks fine. Is the zone AD integrated?

It also appears there is more than one DC. If so, and if there are multiple
sites and/or domains, is there any problem at any of the other sites or on
the other DC/DNS?

Yes it matches exactly.

Yes the host records revert back (I have not rebooted this box since I
started, no confirmation). This info came from the guy doing the job before
me and I dont want to reboot to find out if he is correct (although I agree
it does sound odd!). I'm hopefully bringing another DC online this week and
putting DNS on the new box as a secondary DNS server, then I will try to
reboot the older server!

Looking at advanced view, what difference does it make?
How can I tell if it is AD integrated (2000 AD), I always thought it was?
The DNS server address details are DHCP'd out.

Yes more than one site, the others are out of my control but no issues I
know of. This DC with the DNS service on it is one of 3 DC's. All others
reporting no problems I can see.

I understand I'm not making this post/topic very clear, however I'm new to
DNS on this scale and I'm just getting to grips with it so bare with me!

Thanks.

If the zone is AD integrated, you do not want to make the new DC DNS server
a secondary or it will cause major problems. Just install DNS on it and wait
for the zone to auto appear.

DHCP'd out? I am not sure what that means. Are you saying this domain
controller has a DCHP address? A domain controller should never be a DHCP
client. Unless I got mixed up and you are talking about a different machine?

Ok, just to clarify. I bring a new DC online and install the DNS component.
I leave it? Don't make it a secondary. Let the zone appear then? This will be
my first windows 2K3 DC in a W2K AD environment, should this cause any
issues? (All my application servers are W2K3 it's just the AD that needs
updated).

DHCP'd out? I am not sure what that means. Are you saying this domain

This is the classic example of you not being able to read my mind! All my
servers have static addresses. What I meant was the details/IP address of the
DNS server are given out to the clients via DHCP.

Thanks.

What this means is what DNS addresses are your DHCP servers assigning to the
DHCP clients?
All servers and clients, whether static or DHCP, must use the internal DNS
server only for DNS, this is usually the DC's IP address.

The DNS/DC address is as per the IPCONFIG I posted. This is the IP address
of the DNS server. All clients/servers are configured to look for DNS from
this address.

Ok, it is correct then. It was not clear that DHCP was also assigning this
address.
As for the Event ID 3000's, those are run-time events cause by other event
happening in rapid succession, they are typically caused by rapid zone
serial incrementing, zone transfers and other informational events. In order
to tell you what is causing the 3000 events, you will need to look at other
events preceding the 3000 events. As I said, the preceding events need not
be errors, they can also be informational events and typically are.
If you see many Event 3150 events, the usual culprit is Standard Primary
DDNS zones. ADI zones do not log these events because the zone serial is
meaningless to ADI zones and is not used for updating other ADI zones. I
recommend you convert the zone to ADI, unless it is a zone serving a public
domain.

You are right. I have tried so many times to read someone's mind, especially
my wife's, only to be disappointed because I can't. Darn. But I'm not giving
up - I'm still working on it.

If this is the only new DC you are bring online, meaning it is not a replica
being added in an existing domain, then I would to assume that DCPROMO
created the zone for you. Is this correct? If so, is the zone AD integrated?
That would be default, meaning it will probably say it is a Primary Zone
with the check box checked to store the zone in Active Directory. If it is,
what replication scope is it set to (bottom, middle or top button)?

We are not public facing and I have now changed the zone from a Standard
Primary to ADI. You were correct the event 3000 ID's are all proceeded by
event 3150 from the same zone every time. The zone it is coming from is large
and is over a slower VPN link? The frequency of the event 3000 have settled
down in volume in the past weeks from about 10 entries a day down to 2 or 3
entries.

As stated above the zone is now ADI. How can I tell what the replication
scope is set too? I have looked but obviously in the wrong place?

In the zone properties, the part thatthe radio button is set to either
(shown in order top to bottom):

ALL DNS Servers in the Domain
All DNS servers in the Forest
Domain controllers in the Domain - Windows 2000 Compatible

Ace,

I'm losing the plot here again. I can’t see the 3 listed properties you
speak of. I go into the properties of my zone, then on the general tab, I
have type = ADI. I click change and can change from Primary to Secondary.
This is the only radio buttons I can see?
