[Samba] problem joining a samba PDC from WIN7 clients

[ESGLinux]

Hi All,

I have running a PDC with samba and with my WinXp clients I have no problem
but when I try to join the Domain with a Win7 I get the next error:


[2011/09/15 14:15:58, 0] rpc_server/srv_netlog_nt.c:_net_auth_2(478)
  _net_auth2: creds_server_check failed. Rejecting auth request from client
MACHINE-WIN7 machine account  MACHINE-WIN7$
[2011/09/15 14:15:58, 0] rpc_server/srv_netlog_nt.c:_net_auth_2(478)

In the Win 7 machine I get the message that I have joined the domain, but I
can´t get log in.

I have followed the instrucctions of several posts:

http://wiki.samba.org/index.php/Windows7

But I don´t solve the problem,

any sugestion?

Thanks in advance
