[Samba] Samba 3.0.8 + AD 2003 + Windows 2000

[BATARD olivier]

Hello,

I'm trying to integrate a samba server in 2003 AD. I've read different
howto, And I've integrate computer with net ads join with success. Kinit
user works fine. smbclient -k works fine too.

But when I try to make a net use * \\server\share on a 2000 member server,
I've the following error : 

error 1311
There are currently no logon servers available to service the logon request

On any windows 2003 server it works fine !

I've tried to disable smb signing on both side, no change. 

Here is my global section of smb.conf :

 workgroup = groupesigma
        netbios name = necpiii866-02
        realm = GROUPESIGMA.FR
        security = ADS
        wins server = 89.131.0.80
        encrypt passwords = true
        password server = *
        smb passwd file = /etc/samba/smbpasswd
        unix password sync = Yes
        passwd program = /usr/bin/passwd %u
        pam password change = yes
        username map = /etc/samba/smbusers
        obey pam restrictions = yes
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        local master = no
        os level = 33
        domain master = no
        preferred master = no
        dns proxy = no
        preserve case = no
        short preserve case = no
        default case = lower
        case sensitive = no
#       allow trusted domains = yes
        nt acl support = yes
        winbind separator = +
        winbind cache time = 10
        winbind uid = 10000-20000
        winbind gid = 10000-20000
        winbind enum users = yes
        winbind enum groups = yes
        client signing = yes
        use spnego = yes

Thanks for help.
