strange problem \\ip do not work \\hostname works!

Very strange error, I will appreciate your help

When I'm trying to connect to a remote share from a Xp client to a W2000
server by IP, It doesn't work, It continously prompt user validation.
When I try by hostname It's work, very strange!

Both Machines are in the same domain, across a Wan link , Xp client at one
side with the DC and the Windows Server at the other side.
There isn´t a firewall filtering the link

At the server an event 5719 "No windows NT or DomainController available...
The remote procedure call failed and did not execute" appeared every 2 hours.

It seems a "ntlm" problem, I activated the netlogon.log
why the NlSessionSetup: Session setup Failed?
It has some relationship with my problem, thank's in advance


this is the output

08/06 12:23:52 [CRITICAL] AMERDM: NlSessionSetup: Session setup: cannot
I_NetServerReqChallenge 0xc002001c
08/06 12:23:52 [MISC] Eventlog: 5719 (1) "Domain-Name" 0xc002001c c002001c

stupid question: are you sure of the ip (dhcp...) ?


if you issue a nbtstat -a ip, do you get the windows netbios name ?

Do you use the FQDN or the netbios name ?

Can you try:
nslookup hostname
ping hostname


You may then clear the dns cache
ipconfig /flushdns
clear netbios cache:
nbtstat -R

Mathieu than you for your reply,
The problem is very strange because I can access the resource by name but
not per IP.
So I can resolve the netbios name, Actually I have four servers in the same
site that have the same problem.
really strange one

Xp client and the domain controller are at one side of the link, at the other
side is the member server.

The links its a Lan to Lan (2Mbps)

there is not a firewall.

Today I disjointed the member server from the domain and Icouldn´t joint
again.
"There isn`t Domain controller for the domain xxxx" message appeared.

It seem`s like the member server can`t see the DC, some ports firewalled....
My link provider said, is not filtering ports, I will run netdiag today for
troubleshooting.

After some test I discovered , the problem is about "secure channell"
The member server is not creating the secure channell with the DC.
That's why ntlm does not work.

this is the output of nltest , I executed it on my member server.

nltest /sc_query:amerdm
Flags: 0
Trusted DC Name
Trusted DC Connection Status Status = 1311 0x51f ERROR_NO_LOGON_SERVERS The
command completed successfully

Now I have to troubleshoot IT,
