GUID DNS Name could not be resolved

Gary

I have already posted this, but received no response, so I
am trying to reword in hopes that someone may have an
answer.

My Win2K Domain Controller is having DNS issues. I
believe the root of the problem is that its GUID DNS name
could not be resolved. I have listed the error message
from DCDIAG below.

Does anyone know have to rectify this?

Testing server: Default-Site\SERVER_NAME
Starting test: Connectivity
SERVER_NAME's server GUID DNS name could not be
resolved to an IP address. Check the DNS server, DHCP,
server name, etc Although the Guid DNS name
(7942fd1f-bf54-4105-a1d5-45f6824bfbab._msdcs.domain.com)
couldn't be resolved, the server name (SERVER_NAME)
resolved to the IP address (xx.xx.xx.xx) and was
pingable. Check that the IP address
is registered correctly with the DNS server.
......................... SERVER_NAME failed test

DNS
1) Dynamic for the zone supporting AD
2) All internal DNS client NIC\IP properties must specify SOLELY
that internal, dynamic DNS server (set.)
3) DCs and even DNS servers are DNS clients too -- see #2

Restart NetLogon on any DC if you change any of the above that
affects a DC.

Also double check that you have the _Underscore sub-domains
in your DNS server(s) and that all DNS servers are replicated
fully.

(e.g., _msdcs, _sites, etc.)

Herb,
Thanks for the response. I have checked all of the
client properties and they seem to be fine. I also have
checked the underscore sub-domains and they exist as
well. The wierd thing is that if I scroll down through
the options of the underscore entries, each reference to
the server is just the name and a dot (SERVER_NAME.) and
it has no namespace suffix (such as
SERVER_NAME.domain.com). Also, DNS keeps generating a
SERVER_NAME. entry as one of the name servers and it has
no IP associated with it. Meaning there is a SERVER_NAME
host entry (with no Dot), but there is no SERVER_NAME.
entry. IF I delete the Name Server entry, it gets
automatically added back in when I restart DNS services.

I think this is the root of the problem, but I can't
figure out where the SERVER_NAME. entry is being generated
from.

Any thoughts?

Do you have:

1) At least a TWO-TAG domain name?

2) Each server, especially DC & DNS server, completely
named (with domain name) in each's System Control Panel

[If not, fix #2 and ask here or search Google for the fix
to #1 -- both are very bad.]

Server_name by itself would be fine since that would
append the full name on there, but the "." (dot) terminates
the name.

The normal case is that the full name is actually written out
in there with the terminating dot, e.g., server.domain.com.

1) I am not familiar with the term two-tag, but I am
assuming you mean something like "mycompany.com", if so
the answer is yes. It was all functioning prior to me
adding a second card to the server. I was trying to add a
private network for administrative purposes. The Domain
Name is properly registered and functioning in DNS, except
for that server. entry. I have since taken the extra card
out and I am just trying to get things stabalized and back
to normal.
2)Yes, the server name and domain name are all correctly
listed in the System's Control Panel. On DC you don't
even get the option to modify those. They are
automatically generated there with the domain name when
you promote it to a DC.

That is the thing, I can't figure out where it is getting
the server. entry from? Of all the utilities that I have
run, nothing really states any problem except the GUID
error below from the DCDIAG utility. The other stange
thing is that when I run NETDIAG it doesn't list anything
for the DC Host name? All of the tests pass, but I have
to think no Host name is a problem.

I have been wrestling with this for a few days. Do you
know of any utility that will reset the GUID settings in
the error below. Or any other brute force method that will
get me up and runnig?

Yes. Domain.com, not just domain.
2)Yes, the server name and domain name are all correctly
listed in the System's Control Panel. On DC you don't
even get the option to modify those. They are
automatically generated there with the domain name when
you promote it to a DC.

But it is possible to have them set wrong and either do the
DCPromo (I have never done this so not sure quite how)
OR make it a DNS server without a proper domain name.
That is the thing, I can't figure out where it is getting
the server. entry from? Of all the utilities that I have

error below from the DCDIAG utility.

If you have multiple NICs, make sure the NIC DNS setting
isn't overriding the proper DNS name (there is a box for
NIC specific settings.)
The other stange

for the DC Host name? All of the tests pass, but I have
to think no Host name is a problem.

No.
