Cannot log on to domain

[Guest]

I have XP Pro SP2 , I cannot log onto a domain.The error message says
0x0000267C_DNS_ERROR_NO_DNS_Servers.
I can however ping the server and access the Internet through our Proxy
Server

I have other machines with XP pro SP2 and they authenticate and log on fine.
Any ideas why I am experiencing this problem.

Getting desperate .....

This is a DNS problem.
It's saying there are no DNS servers configured.

Do an ipconfig /all and see what DNS servers are listed.
It should only be the internal DNS servers which host the
domain's records, not an external ISP's DNS server.

Then test the DNS lookup like this:

Go to a command prompt.
Type "nslookup".
Then type "set type=all"
Then type "_ldap._tcp.dc._msdcs.domainname
(where domainname is the name of your domain).

Nslookup returns one or more SRV service location records in the following
format:

hostname.domainname internet address = ipaddress

where 'hostname' is the host name of a domain controller, 'domainname' is
the
domain to which the domain controller belongs, and ipaddress is the domain
controller's Internet Protocol (IP) address.

Then 'exit' will quit you out of nslookup.

Here's a screen-dump of me doing this on an XP machine joined to my domain,
"homenet.local.":

C:\Documents and Settings\Ron.HOMENET>nslookup
Default Server: homenetdc01.homenet.local
Address: 81.187.191.78

( Check that the IP address of the DNS server being queried is correct.
You may get a warning if it can't reverse lookup the name of the default
server, this is sloppy but non-fatal. )

set type=all
_ldap._tcp.dc._msdcs.homenet.local.

Server: homenetdc01.homenet.local
Address: 81.187.191.78

_ldap._tcp.dc._msdcs.homenet.local SRV service location:
priority = 0
weight = 100
port = 389
svr hostname = homenetdc01.homenet.local
homenetdc01.homenet.local internet address = 81.187.191.78

exit

Do you get the same?

R-click in your command prompt window, and select 'mark';
Highlight all the text, starting with the line where you invoke nslookup,
just like I did.
Hit 'enter' to copy the highlighted text.

Reply to this post and place the mouse cursor in the reply window,
and hit Crtl-V to paste the dump into a reply.

Hi Ron , Thanks for the info , find below results of "nslookup" , If I look
from the server side I cann see the machine on the network , but I still
cannot log onto the domain.All the machines I have logged onto the domain
with are using XP Pro SP1.It seems as if XP Pro SP2 could be the problem
Your help is greatly appreciated

Well, there's your problem right there.
There are no DNS servers configured.
( Which is what the original error message said. )
It's trying to use itself (127.0.0.1 ) as a DNS server.

This is most certainly not an SP2 problem! All my machines are SP2.
It's a straightforward DNS misconfiguration.

You need to point it to the DNS server which hosts the domain.
That will probably be the server at 10.0.0.1, since it's providing WINS and
DHCP too.

I'm surprised it's not picking this up from the server at the same time it
picks up the IP address via DHCP. I'm guessing that the server must be
issuing this properly, because the other clients work OK. Do an IPCONFIG
/ALL on a working machine, and you should see DNS servers listed in the
output, like this:

C:\Documents and Settings\Ron.HOMENET>ipconfig /all

Go to the Network Connections folder,
R-click the LAN connection, choose 'Properties'.
Scroll down to Internet Protocol (TCP/IP) and double-click it.

I'd expect it to be set to 'Obtain DNS server automatically.'

Whilst we're here, click the 'Advanced' button and go to the DNS tab.
There should not be any DNS servers listed here, it should be using the ones
asigned by the server.
As a workaround, you could try manually Adding 10.0.0.1 here.
But only as a temporary workaround.

Also on the DNS tab, 'Append Primary.. 'and 'Append parent..'should be
checked.
'Register this connection' should also be checked.

OK your way out of this.

I'm also a bit suspicious that the Primary DNS suffix is not listed
correctly.
Go to My Computer | Properties | Computer Name tab.
'Change' button
'More' button
The Primary DNS suffix should be the full name of your domain.
Also ensure the check-box 'Change primary DNS suffix when domain membership
changes' is checked.

I'm a bit doubtfull that this machine joined the domain properly given its
current configuration.

Get it to the state where it can pick up it's DNS settings from the server
the same as the other machines, and it's primary dns suffix is correct, and
it's set for Dynamic DNS update. Once DNS is fully working ( re-try the
nslookup command ) then if there remain domain oddities, I'd remove it from
the domain and re-join it to the domain now that DNS is functioning.

Thanks for all the Help Ron,


I eventually found out there was a 3rd party spoofed firewall lurking in the
depths of the software

Hi Ron are you any good with Exchange 5.5 Sp4



I have a old exchange 5.5 server and am getting seriously spammed and
relayed.If i go to internet mail service - queues and look in the outbound
messgaed queue , there is plenty mail and it has no originator , just < >
signs , how can I block this form of relaying or spam ?
