Re: DC could not be contacted NT4 domain

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

You could try putting in a specific entry for the logon operation. eg

IP address "domainname \0x1c" #PRE

The domain name must be padded with blanks to 15 characters. The special
character \0x1c must be the sixteenth character. The quotes are essential.

Hi Bill,
I did try adding a line to the lmhosts file
ipaddress dcname #PRE #DOM:domainname
and then I could ping the dc by name.
However when I try to join the domain, after a few seconds, I get a dialog
saying that the domain controller could not be contacted.

That confirms that you have a name resolution problem. To fix it without
WINS, you need to go back to putting an LMHOSTS file on the client to
resolve the name to its IP address.

See KB119495 for a list of the Netbios special names. <domainame
1c> is the special name you need to find the PDC to log on.

Hi Bill,
Using ping, the laptops cannot find the domain controller or any machine
by name, only by ip.
BTW I'm not ignoring advice to set up the wins server, I just want to
understand how I can join the domain for the existing non laptop
machines.

Tony

The reson for suggesting a WINS server is that NT4 uses the special
Netbios name <domainname 1C> to find the domain controller. If
you are running WINS and all machines are set up as WINS clients, this
works smoothly because the clients will get the IP address for the
domain controller from WINS.

If you are not running WINS, the clients will need to get this by
using broadcasts. Obviously this isn't working for your laptops. Can
they ping the server by name? If not, can they ping it by its IP
address?

Hi,
Both of the replies refer to setting up a wins server, or making sure
the settings are correct for the wins server. Why do laptops need a
wins server, and standard pc's do not ? As I explained other machines
can be added to domain with no problems, just not the two laptops ? All
machines use dhcp.
BTW I do not run a wins server, and never have.

Tony

Do you have WINS server? If yes, make sure the new laptop have correct
WINS settings.

I have a NT4 domain controller, which has been running for
years,with a
number of pc's, running win2000 or xp professional sp2 connected to
the
domain.
Recently we have bought a couple of laptops with xp pro sp2, but I
cannot
add these to the network ? I run network id on the laptop, enter our
domain
name, and it immediately reports cannot find domain controller.
Other machines still can be added to the domain with no problem, but
not the
two laptops ?
Any ideas ?
Regards
Tony
