Steven...

Several things...

1. bmp files tend to be large. If you're going to capture the screen and
save it as a .bmp file. Re-open it in pbrush and you will be able to save
it as a .jpg file. Then we will not have to download files greater than
..5Mb. Even better, displaying the text here is even better.

2. If you're a 'network technician' then you realize and appreciate that the
computer provides error messages and being specific is crucial. If
possible, use a spelling checker since your words are all we see and are
equivalent to your appearance would be in person.

3. If you're having a problem with DNS, it helps to provide your setup, and
ipconfig /all from any systems involved.

HTH...

My apologies,

I use Office 2003 and unlike Office XP it does not have Photo Editor so i
can't use Paint to save a JPEG.

My setup i have 2 servers running AD and one has DHCP and DNS on it.
i tried to create a 2nd DNS Server and that did not work well so i
removed it and for some reason that killed DNS on the existing server.
upon recreating the AD Integrated zone it appeared to function again but
those errors are there.

7062 errors can be caused by any of several configuration problems, and it
is most likely configuration.
1 Forwarding to itself. Check the Forwarders list on both and make sure it
is not forwarding to itself. It should not forward to your other DNS server,
UNLESS this one is a child and the other is its parent, even then never
forward a parent DNS to the child DNS. The child's name would be resolved by
using a delegation for the child name on the parent. Another serious
mis-configuration is when you forward two DNS servers to each other, this
sets up a DNS loop that can cause the DNS server to max out the CPU and
cause the service to fail.

2 Delegating a child name to itself unless it holds the child zone.

3 Sending a zone transfer to itself or notifying itself of a zone transfer.
This can also be caused if you have selected allow zone transfers or Notify
to the name servers on the Nameserver tab. Incedentally, if both of the
servers are domain controllers and they are in the same domain, I would
suggest you use Active Directory Integrated zones which will replicate the
zone to both DNS servers through AD, then you should disable zone transfers
altogether.

The nslookup message is simply a message that says nslookup can't find the
PTR record for the IP of the DNS server it is using. Hence, "Can't find
server _name_ for address 172.16.0.1"
 
i no longer have a secondary DNS Server anymore because it appear to update
properly.

I rebuilt the zone on the primary server because the zone info vanished.

Forwarders is unchecked, as far as i'm aware of i dont have child domains.
Zone Transfers are also not enabled, on the face of it it's set up right as
a single AD Intergrated DNS Server.

anything else i need to look at?

A delegation looks like a grayed out folder, when you select it will have an
NS record in the right hand pane.

I've usually seen setting a forwarder eliminates 7062's.

Also curious, there is no gateway address. I am to assume that there is no
Internet access?

Also, this befuddles me:
IP Address. . . . . . . . . . . . : 172.16.1.1
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :
DHCP Server . . . . . . . . . . . : 172.16.0.1
DNS Servers . . . . . . . . . . . : 172.16.0.1

I know the 255.255.0.0 encompasses both 172.16.0.1 and 172.16.1.1, but is
this a typo or was it meant to be?

Also, be wary of the 172.16.0.0 private range. It is NOT a /16 subnet
(255.255.0.0), but rather a /19 subnet (255.255.224.0) subnet, that
encompasses 172.16.0.0 thru 172.16.39.255. The remainder of the subnet is
public, which AOL is an example that uses IPs in that range. So there maybe
some overlap.

As for the lack of a PTR for the nslookup message (not really an error),
create a reverse zone and make sure your DNS server has a PTR entry.

Also, not sure what you mean by "not having a photo editor". Goto Start/Run,
type in mspaint, and Paint pops up.

I use a ISA Proxy Server that is on 172.16.0.2

I know the 255.255.0.0 encompasses both 172.16.0.1 and 172.16.1.1, but
is this a typo or was it meant to be?

Yes that is ment to be and it's a Windows Default and works.

Also, not sure what you mean by "not having a photo editor". Goto
Start/Run, type in mspaint, and Paint pops up.

look at http://www.sj2k.net/dns/MS_Paint.bmp
that's my MS Paint save as dialogue box

Just o clarify on my previous comment, 172.16.0.x are for servers and are
static, 172.16.1.x are for workstations and are leased by DHCP from the
main AD Server that's on 172.16.0.1

Diudn't realize you are using ISA. So I assume that you are using it just
for Web caching and possibly as a firewall? I'm going to assume you are not
using it as a secure NAT since no gateways are on your machines.

Ok, thought you meant something else. Apologies. You could save it as lesser
quality such as 265 so it's still readable but not as large a file.

Can we see a bmp of your DNS console with all your zones expanded?
Is there still a reference in the nameserver list or zone transfer tab for a
DNS server that no longer exists?

Nothing in zone tansfer disabled, name server has the only server i use.

I found a "root hint" that was was for it self and removed it.

the tab description says root hints for usd to find OTHER DNS servers on
the network since i dont have any other servers i removed it.

i hope that stops it.

My DNS Issues have gone away after removing the root hint to it self.
If i have any more DNS Issues that i cant fix i'll be back,

thanks :-)

I would have never thought to ask if you changed anything in the Roots. I
would assume that would cause it. Usually the best practice is to leave the
Roots alone and use forwarding/delegation for the same results.
