[Samba] Samba LDAP PDC BDC quit working

[Philip Washington]

We have had a Samba LDAP-PDC-BDC system setup for close to 3 months with 
about 60 computers in the domain.  Earlier we had a power outage and 
about 30 computers no longer were able to log into the domain or 
authenticate.  Some were NT Workstations and some were W2k.  But not all 
NT or W2K workstations were affected.
If we went to network neighborhood we would see the error message
" "The trust relationship between this workstation and the primary domain
failed"
When someone tries to login to these computers then they get the error
"The system cannot log you on to this domain because the system's 
computer account in it's primary domain is missing or the password on 
that account is incorrect".

We were able to fix the problem on the computers by taking the computers 
out of the domain and re-entering them into the domain.    Went into 
System->Network Identification-> put the machine in a workgroup -> 
reboot -> Go back in and put the machine back into the domain.  No 
manual deletion on the PDC was done.  This was all done on the client.

I reviewed LDAP backups and thus far have not found any descrepancies 
with the systems profiles before or after the power outage.  The records 
indicate that there has not been any change in the LDAP information in 
the last 2 months for the machines which have the problem.  Of course 
once the systems have been relogged into the domain the SambaNTPassword 
changes.

I am currently both baffled and concerned as to how or why this would 
happen.  If anybody could shed more light on what could have happened I 
would appreciate it.
I would also like to know if there is a way to re-add or add a client on 
the Samba-LDAP-PDC instead of going to each individual client.
