DNS issues

I very new to DNS so please bare with me :-)

Here is what I have set-up.

I have created a virtual domain called "exchangetest" (on
a totally different network) and yes without the .com or .
anything.
I have one DC, one server and one win2k pro.

The DC has DNS, DHCP installed and SP4
The server has exchange 2000 standard and SP3 installed on
it.

On the DC I have reverse lookup zones set-up. I can
retreive the correct information from an nslookup from the
exchange server to the DC.
After I installed Exchange I tried to add a user in active
directory on the exchange server, but I received the
following error messages...

Error Message - Windows cannot validate the uniqueness of
this proposed user name with a global catalog server
because: The server is not operational. Windows will
create this user account, but the user can log on only
after the user name is verified to be unique. For further
assistance, contact your system administrator.

If I click on OK and try and proceed to create an exchnage
mailbox for the same user I receive the following
message...

The specified domain either does not exist or could not be
contacted.Facility: Win32ID no: c007054bMicrosoft Active
Directory - Exchange Extension.

I have tried a few things that I found on the web, i.e reg
keys, but I can't seem to find the keys they are talking
about. I tried ipconfig /registerdns, but to no avail.

I'm sure it's to do with the domain name "exchangetest"
without the .com. Not sure though.
But our proper domain that we have set-up is
called "example" (without the .com etc) and exchange works
fine, we have other issues but exchange is ok. I need to
be able to replicate the "example" domain on my virtual
network, but I can't create a new user in the active
directory on the exchange box. The exchange installation
was fine and no errors popped up.

Any idea's, I'm really stuck.
Any information would be gratefully received
Thanks

I would reallly need to see the ipconfig /all from the DC and to verify the
DNS name of your AD domain.
If as you say you have created a single label DNS name for the AD domain,
you should be warned there are many problems you will encounter some have no
known workarounds. You can force Registration in the Single label domain
with registry entries but that is only a partial fix and a band-aid
approach. I highly suggest that you do make the registry entries, but only
so registration can take place and that you demote the DC and repromote it
again with a proper DNS name, instead of "exchangetest", you can use
"exchange.test".

Just a thought but I have all this running on the same
machine using VMWare to create the virtual network.

Well, I can see your primary DNS suffix is a single label name. I'm going to
assume that this is also the name of your AD domain, the good thing is this
is a test setup because single label domain names are a real problem. You
would be much better off removing Exchange then demoting this and promoting
it with a proper DNS name, as I stated earlier exchange.test would be OK to
use. Even in a test environment it is next to impossible to make the single
label name work. I say next to impossible because there is no known way to
make it all work together, the single label name just won't resolve properly
in DNS. If you could make it work there are many users that would be
interrested in how you did it. The main hold up as of now is Group policies,
the single label name won't resolve as a domain name. Group policies are on
the \\domainname\sysvol\domainname\policies DFS share and single label
domain names won't resolve correctly.
Try this in a browser window, \\exchangetest\sysvol
 
I tried \\exchangetest\sysvol

and it worked fine from the exchange server...

We have what I have described in this call, the same
enviroment, but obviously a different domain name without
the .com or .anything and exchange works.

Thing is the sysadmin is no longer here, so I can't ask
him.
The reason I need to replicate this is because I wish to
move the exchange server to new hardware and would like to
replicate the existing set-up. So that I can test till my
heart is content.
I understand why it won't work on a single name domain but
what I can't work out is why it is working at the moment
on the real network.

Is there anything I can check on the existing network that
I might be missing on the virtual network?

It cannot find the domain because the DC, being SP4 cannot register in DNS
if it has not had the registry values added. I can guarantee that if you
have not added the registry fixes to the DC, it is logging 5781 events in
the Event log.
 
Hi Kevin,

Is this a single label domain?

Thanks,
Gary
