[Samba] failed to get machine password for account

[Ivan Arteaga]

Hi,

I have a samba server working as pdc, i have xp workstations joined to 
the samba domain working fine but suddenly since last week some of them 
can´t log into the domain and got an error message about the server is 
not available, the strange thing is the other machines can log in 
without problems.
In the /var/log/samba/smbd.log i got the following error when the 
machine tries to log in:

[2008/04/08 08:47:58, 0] rpc_server/srv_netlog_nt.c:_net_auth_2(461)
  _net_auth2: failed to get machine password for account pc_name$: 
NT_STATUS_NO_TRUST_SAM_ACCOUNT

I had to create a new machine account in the server and change the 
machine name in order to get into the domain. I will appreciate any tip 
in order to fix it up.
My OS is centOS 4.4 and samba 3.025xx

Regards,

--Ivan.
