samba - May 2004 - LOGON problem on windows 2000 server

Hello, I have a problem a little complicated .
I have a Samba (3.0.2a) server compiled with ACL support and using a
directory LDAP for the users and groups, and it makes function of PDC.

On the network, I also a WINS server (win 2000 server) whose PDC is
customer.
Always on the network I have w98, 2000 (wrk), XP (pro) clients and three
server win2000 (of which waiter WINS).
This three Windows 2000 servers have problems of connection to the PDC.
Messages of the rvent viewer:
No controller of Windows NT field or Windows 2000 is available for field
CORMAN.
The following error occurred:  %%1722
and

the explorer could not find the list of the servers of exploring Master
\\ADMIN01 on the network
\Device\NetBT_Tcpip_{D0D1?A2-08DD-4BF1-9322-1D66DBC73B0C }.  The data is
the error code.

 In order to try to include/understand what occurs, I made a script which
executed every 10 minutes and which sends a mail to me.
This mail contains the result of an order smbclient towards one of the
machines.
Sometimes, that passes without problem, I have normal posting, but the
majority of the mails ends in:
SPENGO login failed:  No logon servers As I carry out this order with the
option-d10, I have at more the exit of the debug:  session setup failed:
NT_STATUS_NO_LOGON_SERVERS

Somebody can it help me ?
