Domain Controler Unavaiable

Sometimes during logon process on W98 machines, is displayed the erros message:
"Unable to reache the Domain Controller for this domain". And every others tentatives the logon is done.
Is it related to my WINS server ?? Because when I clean the WINS database, everything goes well for a time, but the error starts again.
The DC are always on-line. It doesn't happen with W2K cllits computers.

Thanks,
 
Hi

Maybe this will help.

Windows 2000-Based or Windows Server 2003-Based Computer Is Inaccessible
from the Domain

SYMPTOMS
========
When you try to connect to a Windows 2000-based computer or a Windows
Server 2003-based computer from other computers on the network, you may
receive one of the following error messages.

o From a Microsoft Windows NT Server 4.0-based computer, you receive the
following error message:
Error = There are currently no logon servers available to service the
logon request.

o From a Microsoft Windows 98-based computer, you receive the following
error message
Error 2215: computername is not accessible. The logon server cannot be
found

where computername is the name of the Windows 2000 or Windows Server 2003,
based computer.

The Windows 2000-based computer or a Windows Server 2003-based computer is
logged on to the domain and can connect to everything else on the network,
but Event Viewer shows that the computer cannot contact the domain
controller. The Netdiag utility reports that the computer is logged on to
the domain through cached credentials.

CAUSE
=====
This behavior can occur because the cached credentials allow the Windows
2000-based computer or a Windows Server 2003-based computer to log on to
the domain even though the computer is not communicating properly with the
domain controller. When a domain user attempts to gain access to shares on
the Windows 2000-based computer or a Windows Server 2003-based computer,
the Windows 2000-based computer or a Windows Server 2003-based computer
tries unsuccessfully to contact the domain controller and verify the user's
credentials. Because the computer cannot contact the domain controller, the
errors occur.

RESOLUTION
===========
To resolve this behavior, join the Windows 2000-based computer or a Windows
Server 2003-based computer to a workgroup named WORKGROUP, and then restart
the computer. Rejoin the computer to the domain, and then restart the
computer again. The computer no longer logs on through cached credentials.

Probably is. The downlevel clients lookup the ICh or 1Bh records for domain
controller/pdc on the wins server. Other less likely problems [unless they are
ongoing] are enforcing smb signing on the domain controllers or using an incompatible
lan manager authentication level as W98 can only use LM unless the Directory Services
Client is uinstalled and the registry had been modified to enable NTLMV2 for it. You
could configure a couple W98 computers with lmhosts files for domain access as
described in the KB link below and if they seem exempt from the problem in the
future, then you know it is netbios name resolution problem. The links below may
help. --- Steve
