Hello Guys.....I have a functional domain and I can add
any other computers to it, but for some reason, this
machine "fell off" the domain and I cannot add it....when
i try, I get this error: "The following error occurred
validating the name "CONCORD". This condition may be
caused by a DNS lookup problem. For information about
troubleshooting common DNS lookup problems, please see the
following Microsoft Web site:
http://go.microsoft/com/fwlink/?LinkId=5171"

I have checked out that site, but it just talks about
active directory and we don't even use active directory
here.....I can't seem to figure out what to do at this
point....usually when a machine falls off the domain, I
simply remove it from the domain on the machine, and
uninstall and reinstall the network drivers and re-add it
to the domain and it works, but not this time.....I would
appreciate ANY help you could offer in this
matter....thank you!

Seems odd you would be asking this in a WIN2000 forum
since all Win2000 domains use Active Directory.

You do however likely have a DNS (maybe a WINS issue
if you REALLY are using an NT domain or using an OLDER
client, NT4/9x).

Servers AND clients must be DNS and/or WINS clients if
you use these servers.

For AD (Win2000+) domains, you must use at least DNS, but
older clients (or older domains) will need WINS servers if
you have more than ONE SUBNET (broadcasts work for one
subnet.)

Clients (including servers) must NOT try to specifiy both an
internal AND external DNS server -- use only the INTERNAL.

Actually with Win2000+ you want to STOP doing that;
use "reset" instead.

If running Win2000+ DCs then run DCDiag on each one;
save output to a text file; search for save, warn, error.

Make sure clients (including DCs, DNS, WINS servers)
ALL specify the correct (internal) name servers.

If you have a Win2k or Win2k3 Domain, you _are_ using Active Directory.

Post the ipconfig /all of the DC and the client.

Then you are in the wrong news group, NT4 does not use DNS for locating the
domain, It uses NetBIOS broadcasts and NTLM Authentication.
Netdiag will not help you diagnose this problem much, it is intended to
diagnose TCP/IP problems for Active Directory domain connectivity.
I suggest you post in the microsoft.public.windowsnt.domain newsgroup.

I just assumed this was the Windows 2000 client issue, not
the NT domain issue, seeing as though I am able to add
other windows 2000 clients to the domain.....

Maybe it is and maybe it isn't but to get the best coverage it should be
posted in a group that can help you, since NT4 domains don't use DNS for DC
locator, the nt4 domain group would help you more.

What Kevin said (in other posts), plus:

If you have Microsoft machines/domains using legacy
clients or legacy servers, even Win2000+ if you wish
BROWSING to work, then you are using NetBIOS for
name resolution.

Without WINS, that NetBIOS resolution is inefficient
and likely BROKEN.

A common mistake of UNIX admins who don't understand
Microsoft networking clients and servers is to believe that
"NetBIOS is bad" and therefore "WINS is bad".

Nothing could be further from the truth -- in fact, WINS
servers fix almost all of the "bad" of NetBIOS.

If you have an IP-Microsoft network of any significant
complexity, then you NEED WINS servers and every
client and "server" must be set as a WINS client.

Significant complexity = more than one subnet (usually)

Also, asking a UNIX-DNS/NT4-Domain/Win2000-client
question in a Win2000 SERVER-DNS newsgroup isn't your
more effective option usually, but it sure wastes a lot of
your time and ours if you don't mention that in the first
post.
